Solution

The correct option is C To release glucose from liver cells and glycogenolysis promotion.
The pancreas releases glucagon when the concentration of glucose in the bloodstream falls too low. It is produced by alpha cells of the pancreas. It stimulates liver to convert stored glycogen into the glucose, which is released into the bloodstream and promotes the glycogenolysis. Its effect is opposite to that of insulin hormone. Thus, the correct answer is option C.
