Question

Frog is amphibian because

• A. It has no tail.
• B. It has lungs.
• C. Its tadpole is aquatic.
• D. It lives both on land and water.

Answer 1

The correct option is D It lives both on land and water.

The amphibians were the first vertebrates to invade the land, but they have not fully adapted to terrestrial life. They and their eggs have no protective coat to check evaporative water loss. Therefore, they inhabit damp places and breed in water. This dual mode of life is expressed in their name (G. amphi= two; bios= life).

So, the correct answer is ' It lives both on land and water'.
