The correct option is B Glycogenolysis
Glycogenolysis is the process by which glycogen stored in the liver and muscle cells of animals, is broken down into glucose to provide immediate energy and to maintain blood glucose levels during fasting. Glycogenolysis occurs in the liver and is stimulated by the hormones glucagon and epinephrine (adrenaline). It is the catabolic process where break down of glycogen occurs by the enzyme glycogen phosphorylase.
