Correct Answer: Glycogen

Solution : The correct option is Glycogen.

The animal starch is glycogen. It is a polysaccharide (complex carbohydrate) that acts as a glucose storage form in animals, including humans. Glycogen is mostly stored in the liver and muscles and may be easily converted into glucose when the body requires energy. Glucose is a simple sugar that cells in diverse organisms use as an instant energy source. Cellulose is present in plant cell walls, and serves as structural support; however, it is not employed for energy storage. Chitin is present in arthropod exoskeletons, and fungal cell walls, where it provides structural support.
