The correct choice is glycogen, as it is the primary form in which glucose is stored in the muscles and liver. After consuming food, particularly carbohydrate-rich foods, the body breaks down these carbohydrates into glucose. When glucose levels rise in the blood, insulin is released by the pancreas to facilitate the uptake of glucose into cells, including muscle cells.

In the muscles, glucose is then converted into glycogen, which is a polysaccharide that serves as a readily available source of energy. Glycogen storage is crucial for physical activities; it can be quickly mobilized to meet energy demands during exercise or between meals.

Other options, like insulin, serve a regulatory role in glucose metabolism but are not stored. Fructose is another type of sugar that is metabolized differently and does not directly contribute to muscle glycogen. Glucose itself is the immediate product of carbohydrate digestion but is not the storage form; it must be converted into glycogen to be stored effectively in the body.
