Answer: Blastocyst

Explanation:

The blastocyst represents blastula stage in mammals during the embryonic development. After fertilization, the formed zygote undergoes rapid cell division known as cleavage.

After cleavage the group of approximately 100 cells is produced. This is known as blastula, spherical layer of cells around a fluid filled cavity which is known as blastocoel.

In mammals, this stage of embryonic development is known as blastocyst.
