Solution

The correct option is C Echinodermata
Echinoderms along with other chordates are deuterostomes, that is in their embryonic development the blastopore turns into the anus. The adults are recognizable by their usually five-point radial symmetry and include animals as starfish, sand dollars and sea urchins.
