Solution

The correct option is C Epitoke
The Heteronereis is a sexual phase. In Heteronereis the posterior part has ovary and testis. Epitoke is the posterior sexual part of various polychaete worms that develops from the anterior sexless part.
Whereas, the anterior asexual region is known as atoke.
Hence, option B is the correct answer.
