Answer 1

The correct option is B (a) Dorsal fin, (b) Caudalfin, (c) Anal fin, (d) Pelvic fin

A dorsal fin is a fin located on the backs of various unrelated marine and freshwater vertebrates, including most fish.

The caudal fin is the tail fin, located at the end of the caudal peduncle and is used for propulsion.

The anal fin is located on the ventral surface behind the anus. This fin is used to stabilize the fish while swimming.

Pelvic fin: either of a pair of fins attached to the pelvic girdle of fishes that help to control the direction of movement during locomotion.
