Vedclass · Answer

(D) Segmentation (metamerism) is a characteristic feature where the body is externally and internally divided into segments with a serial repetition of at least some organs.Among the given options:$1$. Porifera (sponges) are asymmetrical or radially symmetrical and lack true tissues or segmentation.$2$. Coelenterata (Cnidaria) exhibit radial symmetry and do not show metameric segmentation.$3$. Mollusca are generally unsegmented (though some show pseudo-segmentation,they are not considered truly metameric).Therefore,none of the provided options (Porifera,Coelenterata,or Mollusca) exhibit true body segmentation. True segmentation is typically found in Annelida,Arthropoda,and Chordata.
