Solution

The correct option is B Echinodermata
  • Chordates and echinoderm animals are called deuterostomes because, during embryonic development, the embryonic blastopore forms the anus.
  • In the case of protostomes, the embryonic blastopore forms the mouth.

Thus, the correct answer is option B.
