Correct Answer

Option D is the correct answer.

Detailed Explanation

The dorsal hollow (tubular) nerve cord is one of the four defining characteristics of all chordates (along with notochord, pharyngeal slits, and post-anal tail). It is present at some stage of development in all members of phylum Chordata. Non-chordates have a solid, ventral nerve cord or other nervous system arrangements.

Hint

This is one of the key features that defines the phylum Chordata.
