Vedclass · Answer

(D) In earthworms,locomotion is primarily facilitated by the presence of $Setae$. $Setae$ are $S$-shaped,chitinous structures embedded in the epidermal pits in the middle of each segment (except the first,last,and clitellum). These structures act as anchors and provide grip on the soil,allowing the earthworm to move forward through muscular contractions and relaxations of the body wall.
