Quizplus · Accepted Answer

Molecular data-based animal phylogenies divide the protostomes into two groups: ecdysozoans and lophotrochozoans. Ecdysozoans are the animals that molt, while lophotrochozoans grow by adding mass to an existing body. Therefore, option C, ecdysozoans, is the correct answer. Options A and D are incorrect as they are not related to the given question. Option B is also an incorrect choice as it refers to a group of animals without any specific characteristic related to molting or growth.
