Question

Body is metamorically segmented in:
Options
A Porifera
B Annelida
Correct Answer
C Coelentrata
D None of these
Correct Answer

Option B is the correct answer.

Detailed Explanation

Annelida (segmented worms) exhibit metameric segmentation, where the body is divided into a series of repeated, similar segments (metameres) along the anterior-posterior axis. Porifera (sponges) lack true segmentation; Coelenterata (cnidarians) have radial symmetry but no metameric segmentation.

Hint

This phylum includes earthworms, leeches, and polychaetes, all known for their segmented bodies.
