Correct Answer: Option (C) — A is true but R is false

Concept & Option Breakdown

Standard Reference Verified

Assertion (A) is true: Alcohol (such as whisky) acts as a potent diuretic, promoting diuresis and frequent urination.

Reason (R) is false: Alcohol suppresses and inhibits the release of vasopressin (antidiuretic hormone - ADH) from the pituitary gland. With lower ADH, renal collecting ducts cannot reabsorb water, causing excessive excretion of dilute urine.

Elimination Heuristic & Exam Approach

Vasopressin stops urination (anti-diuretic). Since alcohol increases urination, it must INHIBIT (not speed up) vasopressin.
