Answer:
The correct answer is C. It is not true of deuterostomates that the mouth forms from the blastopore.
Explanation:
Deuterostomates are a group of meta-zoises celomated with bilateral symmetry that have the oral opening not derived from the embryonic blastopore, but formed in a secondary way.
The segmentation of the egg is generally radial and the blastopore forms the anus. The mouth forms from the ectoderma and the mesoderma is formed by enterocele. The discussion about the phylogeny of deuterostomates and protostems has not been fully established.
