The development of the embryo is starts with the blastocyst which made two layers. These layers give rice to a complete new born.

Embryology:

It is the branch of science that deals with the development of embryo and classify the stages of development.

Therefore, the development of the embryo is starts with the blastocyst which made two layers. These layers give rice to a complete new born.

The correct answer is given below and attached as an image as well.

Explanation:

Blastocyst forms during the stage early embryonic developmental of mammals. The outer cell layer of the blastocyst is known as trophoblast. This outer cell layer gives rise to extra-embryonic membrane - chorion.

The epiblast leads to the development of ectoderm, mesoderm, endoderm known as the three germ layers. It also forms an extra-embryonic layer called the ambion.  Yolk sac and allantois are formed with the help of hypoblast.
