 Option A is the correct answer.

Trochophore larva is a small, translucent, free-swimming larva characteristic of marine annelids and most groups of mollusks. Trochophores are spherical or pear-shaped and are girdled by a ring of cilia the prototroch, that enables them to swim. In some mollusks (such as gastropods and bivalves), the trochophore develops into a second stage, the veliger, before metamorphosing to an adult form.
