Solution
The correct option is A cocoons
Mature sperm, ovum and nutritive fluid are deposited in cocoons produced by the gland cells of clitellum. Fertilization and development of the zygote happens in these cocoons which are deposited in the soil.
The spermatheca stores sperms that the earthworm receives from its mate during copulation.
Clitellum is a thick glandular structure found in the 14th to 16th segments. It produces a slimy liquid which forms the cocoon.
