Quizplus · Accepted Answer

Protostome development is generally characterized by determinate cleavage, meaning that each cell in the developing embryo has a predetermined fate.

Answer: D
 Another defining feature of protostome development is that the blastopore becomes the anus, with the mouth forming later from a secondary opening. This is in contrast to deuterostome development, where the blastopore becomes the mouth and the anus forms from a secondary opening.
