Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). In the light of the above statements, choose the most appropriate answer from the options given below:
- A is false but R is true
- Both A and R are correct and R is the correct explanation of A
- Both A and R are true, but R is not the correct explanation of A
- A is true but R is false
Answer
(2) Both A and R are correct and R is the correct explanation of A
Solution
Homologous organs share a common anatomical origin and basic structure but may perform different functions. The forelimbs of humans and bats share a similar pattern of bones (humerus, radius, ulna, carpals, metacarpals, and phalanges), which makes them homologous and provides evidence of common ancestry. Hence, both A and R are correct, and R correctly explains A.
