(D) The locomotion in earthworms is a coordinated process involving multiple components:$1$. The contraction and relaxation of circular and longitudinal muscles create waves of movement.$2$. The $Setae$ (bristles) act as anchors to provide grip on the substrate.$3$. The coelomic fluid acts as a hydrostatic skeleton,providing rigidity to the body segments during movement.Therefore,the correct answer is $D$.
