Solution

The correct option is B Segments 14 - 15 - 16
The clitellum is a thick glandular and nonsegmented section of the body wall in the form of a prominent circular band, present in segments 14-15-16 in the earthworm. Clitellum secretes mucous and albumin which helps in the formation of the cocoon and is used for fertilization of eggs.
So,the correct answer is 'Segments 14-15-16' .
