Assertion (A) : Appendix is a vestigial organ in human body. 

Reason (R)    : It does not participate in digestion. 

  • 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.A is true but R is 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.

The appendix is a vestigial remnant of the caecum, which in herbivores digests cellulose. In humans it takes no part in digestion, and its removal has no effect on it - which is exactly what makes it vestigial. Both are true and R explains A.
