Quizplus · Accepted Answer

The blastocyst is the stage of development during which the fertilized egg undergoes several divisions and forms a hollow ball of cells. This stage is characterized by the differentiation of the inner cell mass, which will later become the embryo, and the outer layer of cells, which will form the trophoblast, the precursor to the placenta. Therefore, the correct option is D.
