Vedclass · Answer

(D) $1$. Starch is a polysaccharide made of glucose units. Its digestion by amylase results in maltose,which is further broken down into glucose. Therefore,the end product of starch digestion is glucose,not galactose. Thus,statement $S$ is false.$2$. Boron is an essential micronutrient for plants,primarily involved in cell wall formation and sugar transport,but it is not a structural component of vitamins in animals or humans. Thus,statement $R$ is false.$3$. Since both statements are incorrect,the correct option is $D$.
