Answer:
Correct Answer: B
Solution:
In Nereis, most of the posterior segment filled with gametes, constitutes the sexual region or epitoke of the worm.
Few anterior segments do not take part in gamete formation, constitute the asexual region or atoke.
Sexually mature worm, with these two regions known as heteroecia and the phenomenon involving transformation of non-sexual individual into sexual individual is referred to as epitoky.
