Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli. The annuli are covered in tiny hairs called as setaes. Setae help the worms move. Each segment contains parts of the organism's excretory, circulatory, reproductive, and nervous system. The head and the rear of the body is not segmented. So, the correct answer is option A.
