Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The body of annelids is divided into segments called metameres, externally ring-like grooves (annuli) and internally by vertical partitions called septa. The external segmentation corresponds to internal segmentation. This phenomenon is called metameric segmentation. Phylum Annelida represents the first group of metazoan animals developing a true coelom with metameric segmentation.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
