C Correct answer
Explanation

Starch and glycogen both are ways of storing glucose, the energy source for the most cells. They both are polymers of glucose, produced by repeated condensation reactions between glucose molecules. When the glucose is needed, they can be broken down by hydrolysis reactions to release the glucose.
