Quizplus · Accepted Answer

Deuterostomes and protostomes are both groups within the Eukaryotic kingdom, specifically within the animal kingdom. They are differentiated by their embryonic development; deuterostomes develop the anus from the blastopore, while protostomes develop the mouth from the blastopore. Despite these differences, they are more closely related to each other than to any of the other options provided, which belong to entirely different branches of the eukaryotic tree (porifera are sponges, diplomonads are a group of flagellated protists, angiosperms are flowering plants, and pteridophyta are ferns and their relatives).
