Answer 1

Answer: (B)

A - 5, B - 4, C - 1, D - 2

The swim bladder is an internal gas-filled organ, that contributes to the ability of a fish to maintain its buoyancy.

Amniotes are a clade of tetrapod vertebrates comprising the reptiles, birds, and mammals, that lay their eggs on land or retain the fertilized egg, within the mother.

The pouch is a distinguishing feature of female marsupials.

The defining characteristic of the deuterostome is the fact that the blastopore becomes the anus.

So, the correct answer is option B.
