Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R . Assertion A : Forelimbs of human and bats are homologous. Reason R : Forelimbs of humans and bats have similar anatomical structure. In the light of the above statements, choose the most appropriate answer from the options given below :

Options

  1. AA is false but R is true
  2. BBoth A and R are correct and R is the correct explanation of A
  3. CBoth A and R are true, but R is not the correct explanation of A
  4. DA is true but R is false

Correct answer

B. Both A and R are correct and R is the correct explanation of A

Step-by-step solution

Homologous organs are those which have the same fundamental anatomical structure and embryonic origin but may perform different functions. The forelimbs of humans and bats have the same basic structural plan, consisting of the humerus, radius, ulna, carpals, metacarpals, and phalanges.
