• A. 14th
• B. 15th
• C. 17th
• D. 18th

Answer 1

The correct option is D 18th

A pair of male genital pores is present on the ventrolateral sides of the 18th segment. Numerous minute pores called nephridiopores open on the surface of the body. In each body segment, except the first, last and clitellum, there are rows of S-shaped setae, embedded in the epidermal pits in the middle of each segment.

So the correct answer is '18th'.
