Question

Assertion (A): Amphibians remained as imperfect group.
Reason (R): Although Amphibians invaded land, they could not adapt completely to terrestrial life.

• 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 and R is wrong.
• D. A is wrong and R is true.

Hint:

Amphibians = part-aquatic, part-terrestrial; incomplete land adaptation.

Answer 1

The Correct Option is A

Amphibians, though among the first vertebrates to venture onto land, still depend on water for reproduction and have moist skin prone to desiccation. Thus, their terrestrial adaptation is incomplete, making both A and R correct, with R being the reason for A.
