Answer 1

The correct option is C Setae are absent in the first, last and clitellar segments of the earthworm

Setae are S-shaped structures present in the epidermal pits of the earthworm. They are present throughout the body of earthworm, except in the first, last and clitellar segments of earthworm. By the extension and retraction of setae, the earthworm can move. The primary role of setae is locomotion.
