Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion: Anger in a person, stimulates the secretion of hormones by adrenal medulla. 

Reason: Adrenaline and noradrenaline are the hormones secreted by adrenal medulla that prepares the individuals for fight or flight. 

In light of the above statements, choose the correct answer from the options given below.

Both (A) and (R) are true and (R) is the correct explanation of (A).  
 

Assertion (A) states that anger in a person stimulates the secretion of hormones by the adrenal medulla. This assertion is true. When a person experiences anger, the body's sympathetic nervous system is activated, leading to the release of hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine) from the adrenal medulla.
Reason (R) states that adrenaline and noradrenaline are the hormones secreted by the adrenal medulla that prepare individuals for fight or flight responses. This reason is also true. Adrenaline and noradrenaline are indeed released into the bloodstream in response to stressors, including anger, and they prepare the body for a fight or flight response by increasing heart rate, blood pressure, and glucose levels, among other physiological changes.
Furthermore, Reason (R) provides a valid explanation for why anger stimulates the secretion of hormones by the adrenal medulla.
