Assertion A: Forelimbs of humans and bats are homologous. Reason R: Forelimbs of humans and bats have similar anatomical structure. Choose the most appropriate answer:
- A.Both A and R are correct 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
Correct Answer
(A) Both A and R are correct and R is the correct explanation of A
Solution & Explanation
The forelimbs of humans and bats are homologous — they share the same fundamental bone plan (humerus, radius, ulna, carpals, metacarpals, phalanges) though they perform different functions. Homology is defined by this common anatomical structure/common ancestry, so the Reason correctly explains the Assertion.
