the answer is 3.

The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoele.

olga_2 [115]
