Answer: option D

Explanation:

In the chordates, defined tissues i. e group of specialised cells with specific structure and functions exist in the chordates. the phylum chordata is grouped under the deuterostome wherein the development of the gut is from the back to the from as compared to the protostome where gut develops from front to back.
