Vedclass · Answer

(B) Plant breeding is the purposeful manipulation of plant species in order to create desired plant types that are better suited for cultivation,give better yields,and are disease resistant. This process involves the selection and hybridization of plants to introduce genetic variation,which leads to the development of improved varieties.The objectives of plant breeding (such as increased yield,improved quality,and disease resistance) are fundamentally similar to the objectives of animal breeding,as both aim to improve the traits of organisms for human benefit.Therefore,both statements $A$ and $R$ are true,but $R$ is not the direct explanation for why genetic variation is obtained through plant breeding; rather,it describes the shared purpose of these disciplines.

$A$: Improved varieties with genetic variations can be obtained through plant breeding.
$R$: The main objectives of plant breeding are similar to those of animal breeding.
