Answer:
Correct Answer: A
Solution:
In annelida, four pairs of flask-shaped sacs, each with a diverticulum for storage of sperms and a large ampulla for their nourishment, is present.
Spermathecae occur in 1-3 segments.
They receive sperm during copulation.
As cross fertilization occurs in earthworms, the sperms of one worm are transferred to the spermathecae of the other.
