Solution
The correct option is C Glycogen
Glycogen is osmotically inactive because of its large size which prevents it from leaving the cell by passing through semipermeable plasma membrane by osmosis so it can be easily stored inside the cell.
Animal cells store food in the form of glycogen. The excess of glucose in the blood is converted to glycogen in the muscle cells. The process of formation of glycogen is known as glycogenesis. During the muscle exercise when extra energy is needed the glycogen is broken down to glucose and channelized into the bloodstream by glycogenolysis.
