- Assertion (A) is true: Alcohol is a diuretic, meaning it increases the rate of urine production, hence increasing the frequency of urination. - Reason (R) is false: Alcohol intake inhibits the secretion of vasopressin (Antidiuretic Hormone - ADH), it does not speed it up. Vasopressin normally reduces urine production by promoting water reabsorption in the kidneys. When ADH is inhibited by alcohol, less water is reabsorbed, leading to increased urine output.
