Assertion (A): Drinking of whisky increases the frequency of urination. Reason (R): Alcohol intake speeds up the secretion of vasopressin in the body.
✓ Correct answer: c) A is true but R is false
ExplanationAssertion (A) is true: Alcohol, including whisky is a diuretic.It inhibits the production of vasopressin (also known as antidiuretic hormone or ADH), which is responsible for regulating water retention in the body.When vasopressin levels drop, the kidneys produce more urine, leading to increased urination.This effect explains why alcohol consumption causes increased thirst and dehydration-related symptoms after drinking.Reason (R) is false: Alcohol actually inhibits the secretion of vasopressin, rather than speeding it up.Vasopressin helps the kidneys reabsorb water, and when its secretion is reduced, the body loses more water through urine, causing dehydration and increased urination.Alcohol interferes with the brain’s communication pathways, affecting areas controlling balance, memory, speech, and judgment.Alcohol slows down the central nervous system, impairing coordination and judgment.Alcohol can cause intellectual impairment, headaches, memory loss, and slowed thinking.464
