Solution
The correct option is B Coccon formation The clitellum is part of the reproductive system. The clitellum is a thick, saddle-like ring found in the epidermis (skin) of the worm, usually with a light-coloured pigment. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. The main function of clitellum is cocoon formation. In earthworms, the clitellum can only be seen when the worm is sexually mature.
