Correct answer: C If assertion is true but reason is false.

The Assertion is true - catecholamines do mobilize glucose during stress. However, NCERT states “Catecholamines also stimulate the breakdown of glycogen resulting in an increased concentration of glucose in blood” - the Reason incorrectly states “glycogen synthesis” instead of “breakdown” making it false.
