D
embryo
Verified step by step guidance

Understand the structure of the blastocyst: The blastocyst is an early stage in mammalian embryonic development. It consists of two main parts: the outer layer called the trophoblast and the inner cell mass (ICM).
Learn the role of the trophoblast: The trophoblast is responsible for forming the outer layer of the blastocyst, which will contribute to the formation of the placenta and other supporting structures for the embryo.
Understand the role of the inner cell mass (ICM): The ICM is a group of cells inside the blastocyst that will develop into the embryo itself, as well as some of the extraembryonic structures like the amniotic sac.
Differentiate between the options: The trophoblast forms the placenta, the amniotic sac is an extraembryonic structure, and the embryo is formed from the inner cell mass.
Conclude that the inner cell mass of the blastocyst is destined to become the embryo, as it contains the cells that will differentiate into all the tissues and organs of the developing organism.
