Solution

The correct option is B
Earthworm

The body of an earthworm consists of two kinds of muscles- circular muscles and longitudinal muscles. Locomotion in earthworm is affected by the rhythmic contraction and relaxation of these muscles. Apart from these muscles, structures projected out from the body called chaetae also help them in locomotion.
