While they may contain small amounts of carbohydrates and negligible fats,their nutritional significance is primarily attributed to their high protein content.

(A) India is one of the largest producers and exporters of tea in the world. Among the given options,tea contributes the most to India's foreign exchange earnings through agricultural exports. While rice is also a major export,tea remains a significant and traditional source of foreign currency for the Indian economy.

(D) Gujarat is the largest producer of cotton in India. The state's favorable climatic conditions,such as black soil and appropriate temperature,make it highly suitable for cotton cultivation. It consistently ranks first in terms of both production and area under cotton cultivation in the country.

(B) Cereals (such as wheat,rice,maize,barley,and sorghum) are the primary source of food for humans and also serve as a major source of fodder for livestock. They provide the bulk of the calories required for human nutrition and are widely cultivated globally.

(B) Noodles are typically made from semolina or flour derived from $Triticum$ $durum$ (durum wheat). $Triticum$ $durum$ is a hard wheat species known for its high protein and gluten content,which provides the necessary elasticity and texture for pasta and noodle production.

(B) Heterosis, also known as $Hybrid \text{ } vigor$, is the phenomenon where the progeny of a cross between two genetically distinct parents exhibits superior traits compared to both parents. This includes increased growth rate, biomass, and fertility. It is a fundamental concept in plant and animal breeding to improve productivity.

(C) Gujarat is the largest producer of groundnut in India. It contributes significantly to the total national production due to its favorable climatic conditions and soil types suitable for groundnut cultivation.

(B) Cotton ($Gossypium$ $spp.$) is the most important fiber-yielding crop in India. It is cultivated over the largest area compared to other fiber crops like jute,flax,and sisal. It plays a significant role in the Indian economy and textile industry.

(A) Among the given options,potatoes ($Solanum$ $tuberosum$) are produced in the highest quantity in India. India is one of the world's leading producers of potatoes,which serve as a staple food crop in the country.

(D) Uttar Pradesh is the leading producer of sugarcane in India. It accounts for the largest area under sugarcane cultivation and the highest total production of sugarcane in the country. This is due to the fertile Gangetic plains which provide ideal conditions for the growth of the crop.

(D) Cotton ($Gossypium$ species) belongs to the family $Malvaceae$. It is the most important and widely cultivated fiber-yielding crop in India. It provides natural cellulosic fibers used extensively in the textile industry. While Jute is also a significant fiber crop,Cotton holds the primary position in terms of economic value and cultivation area in India.

(B) Rice $(Oryza sativa)$ is the primary staple food and crop for a majority of the population in Asia. It is cultivated extensively across the continent due to the favorable tropical and subtropical climate conditions.

(D) The Central Rice Research Institute $(CRRI)$ is a premier research institute under the Indian Council of Agricultural Research $(ICAR)$. It is located in Cuttack,Odisha,India. It was established on $23$ April $1946$ to conduct research on rice cultivation and improvement.

(A) Heterosis or hybrid vigor refers to the phenomenon where the hybrid offspring shows superior traits compared to its parents. In sexually reproducing plants,this vigor is lost in subsequent generations due to segregation and recombination. However,in vegetatively propagated plants,the hybrid genotype is maintained indefinitely through asexual reproduction without the risk of segregation. Therefore,once a superior hybrid is developed,its heterosis can be preserved and multiplied rapidly through vegetative propagation.

(D) Bombykol is a well-known sex pheromone secreted by the female silkworm $(Bombyx \ mori)$.
It is used to attract males for mating purposes.
Therefore,the correct option is $D$.

(D) Pheromones are chemical substances secreted by an animal,especially an insect,which influence the behavior or physiology of other individuals of the same species.
$1$. Bombykol is a well-known sex pheromone secreted by the female silkworm moth ($Bombyx$ $mori$).
$2$. Cinetone and Geraniol are also known to act as pheromones or components of pheromone blends in various insect species.
Therefore,all the given options represent substances that function as pheromones.

(A) Silage is a type of fodder made from green foliage crops which have been preserved by acidification,achieved through fermentation.
In the process of making silage,the green plant tissues are chopped and stored in a silo.
The lactic acid bacteria present in the plant material ferment the carbohydrates (sugars) present in the plant tissues into lactic acid.
This acidification lowers the $pH$ of the material,which prevents the growth of spoilage-causing bacteria and preserves the nutritional value of the fodder for cattle.

(A) $IARI$ stands for Indian Agricultural Research Institute. It is a premier national institute for agricultural research,education,and extension in India,located in New Delhi.

(B) Organisms that cause damage to crops,such as insects,rodents,and other harmful animals,are collectively referred to as $Pests$.
$Pathogens$ are disease-causing microorganisms.
$Pesticides$ are chemical substances used to kill pests.
$Weeds$ are unwanted plants that grow along with the crops.
Therefore,the correct term for components that cause damage to crops is $Pests$.

(D) Weedicides are chemical substances specifically designed to kill or inhibit the growth of unwanted plants,known as weeds,in agricultural fields or crops without significantly harming the main crop.
$A$. Pesticides are used to kill pests.
$B$. Fungicides are used to kill fungi.
$C$. Insecticides are used to kill insects.
$D$. Weedicides are used to remove weeds.
Therefore,the correct option is $D$.

(B) Weedicides are chemical substances specifically designed to kill or inhibit the growth of unwanted plants,commonly known as weeds. These chemicals help in reducing competition for nutrients,water,and sunlight between crops and weeds,thereby increasing agricultural productivity. Therefore,weedicides are used for the control of weeds.

(D) In agricultural and ecological contexts,the term 'pest' refers to any organism that causes damage to crops,livestock,or human property.
While the term is often colloquially associated with insects,it broadly encompasses various organisms including insects,fungi,bacteria,viruses,weeds,and rodents that interfere with human activities or agricultural productivity.

$A$. Insecticides are used to kill insects.
$B$. Pesticides are a broad category of chemicals used to control various pests.
$C$. Fungicides are used to control fungal diseases.
$D$. Weedicides are the correct agents used for weed control.

(C) Pests are organisms that damage crops,livestock,or forestry,thereby causing significant economic losses.
By feeding on plants or transmitting diseases,pests reduce the overall yield and quality of agricultural produce.
Therefore,the statement that its effect decreases crop production is correct.

(D) Nematodes,such as $Meloidogyne$ $incognita$,infect the roots of a wide variety of plants.
These include many important agricultural crops such as vegetables (e.g.,tomato,brinjal),fruits,and cereal crops.
Therefore,nematodes cause diseases in all of the mentioned categories of crops.
Thus,the correct option is $D$.

(B) Since the dawn of civilization,the primary and most fundamental requirement for the survival of humanity has been $Food$. Humans have been actively involved in agriculture,animal husbandry,and food production strategies to ensure a consistent supply of nutrition. While shelter and procreation are also essential,the constant effort to improve food production techniques highlights its priority as the most basic need for survival.

(A) Statement $A$ is true because modern agricultural practices,including plant breeding and animal husbandry,focus on developing high-yielding and disease-resistant varieties.
Reason $R$ is also true because the primary objective of these strategies (animal husbandry and tissue culture) is to enhance food production to sustain the rapidly increasing human population.
Since the production of high-quality,disease-free organisms is a direct method used to achieve the goal of increased food security for the population,$R$ provides the correct explanation for $A$.

(D) To meet the increasing demand for food due to the growing human population,various strategies for enhancement in food production are employed.
$1$. Tissue culture is a technique used for rapid clonal propagation of plants.
$2$. Dairy farming involves the management of animals for milk and its products.
$3$. Poultry farming is the practice of raising domesticated birds for eggs and meat.
All these methods contribute significantly to increasing food production and ensuring food security. Therefore,the correct answer is $D$.

(B) Honey is a product of high nutritional value and also finds use in the indigenous system of medicine. It is known for its medicinal properties,such as being an antiseptic and a soothing agent.
Honey is also used in various cosmetic preparations due to its moisturizing and skin-nourishing properties.
Both statements are factually correct. However,the use of honey as a cosmetic is a separate application from its use as a medicine. Therefore,$R$ is not the correct explanation for $A$.

(C) The correct answer is $C$.
$1$. Anand is home to the Amul Dairy $(GCMMF)$.
$2$. Mehsana is home to the Dudhsagar Dairy.
$3$. Palanpur is home to the Banas Dairy.
$4$. Kheda district is associated with the Kaira District Co-operative Milk Producers' Union (Amul),whereas 'Mahisagar Dairy' is not a major dairy associated with Kheda in this context. Therefore,the pair $C$ is incorrect.

(C) Banas Dairy,also known as the Banaskantha District Co-operative Milk Producers' Union Ltd.,is located in Palanpur,which is the district headquarters of the Banaskantha district in Gujarat,India. It is a major part of the Amul cooperative network.

(C) The White Revolution,also known as Operation Flood,was launched in India to increase milk production. It transformed India from a milk-deficient nation into the world's largest milk producer. Therefore,it is directly associated with the dairy industry.

(D) Dudhsagar Dairy,also known as the Mehsana District Co-operative Milk Producers' Union Ltd.,is located in Mehsana,Gujarat. It is one of the largest dairy cooperatives in India and is a member of the Gujarat Co-operative Milk Marketing Federation $(GCMMF)$,which markets products under the brand name 'Amul'.

(C) In a country like India,where a large portion of the population is vegetarian,milk provides essential proteins and fats. However,to ensure proper human nutrition and to address protein deficiency,the consumption of eggs and fish is highly recommended as they are excellent sources of high-quality animal proteins and essential amino acids. Therefore,in addition to milk,eggs and fish are considered necessary for a balanced diet.

(C) The requirement for $Food$ is as ancient as human evolution itself. Since the dawn of humanity, the search for and production of food has been the primary driver for survival, settlement, and the development of civilizations. While shelter and procreation are also fundamental, the biological necessity for energy intake through food is the most immediate and constant requirement throughout human history.

(C) Since the dawn of human evolution,humans have relied on both plants and animals as primary sources of food. Early humans were hunter-gatherers who consumed wild plants,fruits,roots,and hunted animals for sustenance. Therefore,the use of both plants and animals as food is as ancient as human evolution itself.

(C) Thousands of years ago,human civilization shifted from hunting and gathering to settled life.
Agriculture provided a stable source of plant-based food,while animal husbandry provided milk,meat,wool,and labor.
Both practices were essential and complementary in increasing food production and supporting the growth of human populations.

(D) Agriculture and animal husbandry are dynamic fields that continuously evolve through scientific research,technological advancements,and improved management practices to increase productivity and efficiency. Therefore,both $(B)$ and $(C)$ are correct.

(D) To meet the increasing food requirements of the growing human population, various strategies for enhancement in food production are employed.
$1$. Tissue culture is a technique used for rapid clonal propagation of plants.
$2$. Dairy farm management deals with processes and systems that increase yield and improve the quality of milk.
$3$. Poultry farm management is the practice of raising domesticated birds for food (eggs and meat).
Since all these methods contribute significantly to enhancing food production, the correct answer is All of the above.

(D) The basic requirements for human survival are often categorized as food,clothing,and shelter. Among these,food is the most fundamental and primary requirement because it provides the energy and nutrients necessary for all physiological processes and survival. Without food,the body cannot sustain life,making it the most essential need.

(D) Assertion $A$ is false because breeding between animals of the same breed is known as inbreeding,not outcrossing. Outcrossing involves mating between animals of the same breed that have no common ancestors on either side for $4-6$ generations.
Reason $R$ is false because outcrossing is generally used to overcome inbreeding depression and to increase productivity,not necessarily to produce offspring with completely different traits not present in the parents. In fact,outcrossing helps in maintaining the breed characteristics while improving performance.

(D) The variation in the genetic makeup of animal species is primarily driven by breeding and heterozygosity.
Breeding facilitates the recombination of genes through sexual reproduction,which introduces new genetic combinations.
Heterozygosity refers to the presence of different alleles at a specific locus,which increases the variety of genotypes within a population,thereby enhancing genetic diversity.

(D) Statement $(i)$ is correct: Animal breeding aims to improve the yield and desirable qualities of livestock,including milk production.
Statement $(ii)$ is correct: Different breeds within a species exhibit variations in traits such as size,color,and productivity.
Statement $(iii)$ is incorrect: Out-crossing is the mating of animals within the same breed that have no common ancestors on either side of their pedigree up to $4-6$ generations. Mating between two different species is called interspecific hybridization,not out-crossing.
Statement $(iv)$ is correct: $A$ mule is produced by the mating of a male donkey and a female horse,which is a classic example of interspecific hybridization.
Therefore,only statement $(iii)$ is incorrect.

(A) The correct matching is as follows:
$(i)$ Inbreeding: Mating between animals of the same breed $(i - B)$.
$(ii)$ Out-crossing: Mating between animals of the same breed having no common ancestors for $4-6$ generations $(ii - C)$.
$(iii)$ Cross-breeding: Mating between superior male of one breed and superior female of another breed $(iii - A)$.
Therefore,the correct sequence is $(i - B), (ii - C), (iii - A)$.

(C) The full form of $IARI$ is $Indian$ $Agricultural$ $Research$ $Institute$. It is a premier national institute for agricultural research,education,and extension in India,located in New Delhi.

(B, D) The correct answer is $B$ and $D$.
$1$. $IARI$ (Indian Agricultural Research Institute) is located in New Delhi,not Izzatnagar.
$2$. Single Cell Protein $(SCP)$ is typically produced by large-scale microbial fermentation (e.g.,using Spirulina or Methylophilus methylotrophus),not primarily through genetic engineering.
$3$. Mushroom cultivation is a global industry.
$4$. Biofortified maize hybrids like $Shakti$,$Rattan$,and $Protina$ were developed with double the lysine and tryptophan content.

(C) The mismatched pair is $C$. Hybrid maize varieties are typically developed for high yield and disease resistance,not specifically for high oil content and high quality. High oil content and high quality are traits usually associated with specific biofortified crops or oilseed breeding programs. Santa Gertrudis is a well-known hybrid breed of cattle (a cross between Shorthorn and Brahman). Mushrooms are heterotrophic organisms used as a protein-rich food source. $A$ mule is a hybrid offspring of a male donkey and a female horse,known for being stronger and more resilient than its parents.

(A) $IVRI$ stands for Indian Veterinary Research Institute,which is primarily involved in research related to animal health and livestock,including poultry farming.
$IARI$ stands for Indian Agricultural Research Institute,which is famous for its significant contributions to crop improvement and biofortification (e.g.,developing iron-fortified wheat or vitamin-enriched vegetables).
Therefore,$IVRI$ is associated with poultry farming and $IARI$ is associated with biofortification.
