Vedclass · Answer

(A) The question asks for organisms that exhibit bilateral symmetry and the absence of true tissues (often referred to as 'absence of cells' in some contexts,though biologically it implies the lack of tissue-level organization or specific cellular differentiation). However,in the context of the $Animal$ $Kingdom$,$Ctenophora$ (like $Ctenoplana$ and $Beroe$) are known for their radial symmetry. The question likely refers to the absence of true tissue-level organization. $Ctenoplana$ and $Beroe$ belong to the phylum $Ctenophora$. Note: If the question implies 'absence of true tissues',it is a characteristic of $Porifera$. Given the options,$Ctenoplana$ and $Beroe$ are the standard examples for $Ctenophora$.
