Solution
The correct option is D Involution
During gastrulation, as the blastopore is forming, future endoderm and mesoderm cell layers on the surface of the embryo roll over the edge of the lip into the interior of the embryo, a process called involution. Once inside the embryo, these cells move away from the blastopore toward the animal pole and become organized into layers of endoderm and mesoderm, with the endoderm on the inside. The blastocoel collapses during this process, displaced by the archenteron that is formed by the tube of endoderm.
