Which statement most accurately describes the deuterostomes?

A) The first opening on the embryo surface becomes the mouth.
B) Their food and wastes enter and exit through the same body opening.
C) They have an incomplete digestive system.
D) They have radial symmetry.
E) Their mouth develops from the second embryonic opening.

Deuterostomes

Lineage of bilateral animals in which the second opening on the embryo surface develops into a mouth; for example, echinoderms and chordates.

Radial Symmetry

A symmetrical arrangement in which body parts radiate out from a central point, common in animals like jellyfish and starfish.

Embryonic Opening

The embryonic opening refers to the blastopore, an early stage in the development of an embryo that can develop into the mouth or anus in different animal groups.
