(C) The correct answer is $C$. Echinoderms are considered to be the closest invertebrate relatives of chordates. This is supported by several evolutionary evidences: $1$.

Both possess an enterocoelic coelom,which is formed from the outpocketing of the embryonic gut. Therefore,in the evolutionary hierarchy,echinoderms are placed between molluscs and chordates.
