<h2>c. Division of these two groups occurred after the protostome developmental sequence appeared. </h2>
Explanation:
- Protosomes are such types of organisms in which the mouth part developed first during embryonic development.
- Those animals in which anus develop first are known as deuterostomes.
- This differentiation takes place during the embryonic development of the organisms.
