Answer 1

Answer: (C)

17 and 19

Earthworm belongs to the phylum annelida which are segmented worms. Genital papillae are two pairs of protuberances on segments 17 and 19 on the ventral surface. Each papilla bears a shallow cup-like depression on the top, which functions as sucker during copulation.

So, the correct answer is option C.
