Vedclass · Answer

(A) When a person encounters a sudden threat (like a snake),the body initiates the '$fight-or-flight$' response.This response is mediated by the sympathetic nervous system.The sympathetic nerves stimulate the adrenal medulla to secrete catecholamines,specifically epinephrine (adrenaline) and norepinephrine (noradrenaline).These hormones prepare the body for immediate action by increasing heart rate,blood pressure,and alertness.Therefore,option $A$ is correct because the adrenal medulla is the site of secretion for these hormones,not the adrenal cortex.
