A Correct answer
Explanation

Metameric segmentation is the division of the body into repeated, similar segments (metameres). Annelids (earthworms) show this feature prominently. Arthropods have segmentation, but it's often specialized/fused. Echinoderms, coelenterates, and protozoa lack true segmentation.
