Rows of \(S\)-shaped setae in the body of earthworm are present in all the segmentsexcept
1 The firstlast and clitellum
2 The last segment
3 The first segment
4 The first and last segment
Explanation:
A Setae are the ' \(\mathrm{S}\) ' shaped stiff bristles present or the complete body of earthworm except for the first and last clitellar segments. Setae are chitinous structures that help in the earthworm in locomotion.
