Solution

The correct option is C Peristomium
The first segment of the earthworm, the peristomium, contains the mouth. There is a small tongue-like lobe just above the mouth called the prostomium. Earthworms use the prostomium to see their environment, as earthworms have no eyes, ears, nose or hands. They depend on the prostomium and skin to help it feel their way through the soil.
So the correct answer is 'Peristomium'.
