Vedclass · Answer

(B) The phylum $Annelida$ is characterized by metameric segmentation (metamerism),a closed circulatory system,and a ventral nerve cord. Members of the phylum $Annelida$ are true coelomates $(eucoelomates)$,meaning they possess a true body cavity lined by mesoderm. Pseudocoelom (a body cavity not fully lined by mesoderm) is a characteristic feature of the phylum $Aschelminthes$ $(Nematoda)$,not $Annelida$. Therefore,the correct answer is $B$.
