Assertion (A) : Roughage prevents constipation.
Reason (R) : Roughage adds bulk to the food.

  • A.Both A and R are true and R is the correct explanation of A.
  • B.Both A and R are true but R is NOT the correct explanation of A.
  • C.Both A and R are false
  • D.A is false but R is true.

Answer: A

Correct answer: Both A and R are true and R is the correct explanation of A.

Roughage - the indigestible fibre of vegetables and whole grains - absorbs water and adds bulk, which stimulates the intestinal muscles and keeps the contents moving. That added bulk is precisely how it prevents constipation. Both are true and R explains A.
