Which of the following characteristics defines a chordate? a. radial symmetry, defined tissues, and gut develops from front to back asymmetrical, b. gut develops from front to back, and lacks tissues radial symmetry, c. gut develops from front to back, and grows by molting bilateral symmetry, d. defined tissues, and gut develops from back to front bilateral symmetry, e. defined tissues, and gut develops from front to back

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. Chordates possess bilateral symmetry.
