The correct option is A.

Starch is a polysaccharide that is made up of long chains of glucose molecules. The glucose molecules can be arranged in form of ring or in a branched form. During the process of digestion, starch molecules are broken down into glucose with the help of enzymes and these glucose molecules are used in the body for production of energy. The branching structure of starch is very crucial, because it allow the enzymes to attack the starch molecules at different point for easier breaking down.
