The correct option is C
Both A and R are false.

Glucagon increases blood sugar level and insulin reduces it. They are antagonistic pancreatic hormones. Glucagon converts the glycogen stored in the liver to glucose that leads to an increase in blood sugar. Insulin is the hormone responsible for the cellular uptake of glucose and lowers the blood sugar level.
