Solution

The correct option is D Differentiated into embryo proper
The blastocyst is composed of the outer cell layer called as the trophoblast and the inner cell mass. The inner cell mass will form all the tissues of the embryo and differentiate into embryo proper. The trophoblast will form the placental structures.
Thus, the correct answer is option A.
