Solution

The correct option is D The presence of well-developed skull
Vertebrates belong to the subphylum Vertebrata of the Phylum Chordata. AII 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. So, the correct answer is 'The presence of well-developed skull'.
