• A. Last segment
• B. First segment
• C. Clitellar segment
• D. First, last and clitellar segments

Answer 1

Answer: (D)

First, last and clitellar segments

Setae are the chitinous tiny bristles present on the body of an earthworm. These are helpful in locomotion. Seate help the earthworm to hold the surface and thus prevent it from sliding back during the peristalsis. There are no setae in the first and the last segments and also in the clitellum of a mature worm. So, the correct answer is option D.
