The correct option is D Clitellum
The clitellum is a thickened glandular and non-segmented section of the body wall near the head in earthworms and leeches, that secretes a viscid sac in which the eggs are deposited. It is located near the anterior end of the body (around the 14th, 15th and 16th 17th segments). Its main function is to store the eggs of the worm. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. n earthworms, the clitellum can only be seen when the worm is sexually mature.
So, the correct answer is 'Clitellum'.
