Answer:

Deuterostomes include both phyla echinoderms and chordates, which includes the vertebrates.

Echinoderms and Chordates are more closely related to each other than they are to other animals because the coelom ( an open fluid-filled body cavity lined with tissues) found in the animals of this phylum is made from the digestive tube & the endoskeleton present in the body are composed of 95% of calcium carbonate just like present in chordates.

<em>The correct option is C) C-shaped cartilage rings </em>

The pathway of the trachea is kept open by C- shaped cartilages which are lined all over in the trachea. The C-shaped cartilages protects as well as maintain the shape of the wind-pipe.
