Answer:
Correct Answer: A
Solution:
In annelida four pairs of flask shaped sacs, each with a diverticulum for storage of sperms and large ampulla for their nourishment is present.
Spermathecae occur in 6-9 segments.
They receive sperm during copulation.
As cross fertilization occurs in earthworm, the sperms of one worm transferred to spermathecae of the other.
