Text Solution

Verified by Experts

The correct Answer is:
D
Vertebrates belong to the subphylum Vertebrata of the Phylum Chordata. All vertebrates share a common diagnostic character, the elaboration of anterior skeletal elements into a "cranium" or "skull" which houses various sense organs and a complex brain. The distinctive vertebrate cranium and brain evolved even before the vertebral column and are, therefore, more fundamental characteristic of vertebrates than the backbone.
