The correct option is B Glycogen
Glucose is the carbohydrate transported by the bloodstream to the various tissues and organs, including the muscles and the brain, where it will be used as energy. If the body does not need glucose for energy, it stores glucose in the liver and the skeletal muscles in a form called glycogen. Glycogen stores are used as an energy source when the body needs more glucose than is readily available in the bloodstream (for example, during exercise).
