1. Assertion (A): Drinking of whisky increases the frequency of urination.
2. Reason (R): Alcohol intake speeds up the secretion of vasopressin in the body.
A
Both A and R are individually true and R is the correct explanation of A
B
Both A and R are individually true but R is not a correct explanation of A
C
A is true but R is false
D
A is false but R is true
Correct Answer: Option C
Explanation
1. Assertion (A) states that drinking whisky (or any alcoholic beverage) increases the frequency of urination. This is generally true. Alcohol acts as a diuretic.
2. Reason (R) states that alcohol intake speeds up the secretion of vasopressin (ADH - Antidiuretic Hormone) in the body. This is false.
3. Vasopressin (ADH) normally helps the kidneys reabsorb water, thus reducing urine output. Alcohol actually *inhibits* or *suppresses* the secretion of vasopressin from the pituitary gland.
4. By inhibiting vasopressin, alcohol reduces water reabsorption by the kidneys, leading to increased urine production and more frequent urination.
5. Therefore, Assertion (A) is true, but Reason (R) is false because alcohol suppresses, not speeds up, vasopressin secretion.
