Diagram I shows gastrulation in a frog. The presence of a blastopore and the formation of three germ layers (ectoderm, mesoderm, endoderm) are characteristic of gastrulation in amphibians, which include frogs. Diagram II appears to show a different type of gastrulation in birds, but there is no information to support choice E regarding a comparison between mammals and reptiles. Choice A is incorrect because there is no information to indicate that both diagrams are of the same animal, and Blastulae are only shown in Diagram I.
