Best answer

Correct option is (c)

Explanation of 'A' & 'R' :- Glucagon is secreted by the a cells of the islets of Langerhans. Glucagon acts on the cells of liver and adipose tissue. It stimulates the liver to convert stored glycogen into glucose. Glucagon is also called as anti-insulin hormone. Whereas, insulin is secreted by the ẞ cells of the islets of Langerhans. Insulin is antagonistic to glucagon. Insulin decreases the level of glucose in the blood. It converts glucose into glycogen. When the blood sugar level drops the secretion of insulin is suppressed and when the blood sugar level increases, the secretion of insulin is stimulated.

Result: Hence, it is proved that 'A' is true and 'R' is false, so the answer is option (c).
