The stem cells of a blastocyst are found in the inner cell mass, which eventually develops into the embryo.

Option B is incorrect because the outer cell mass does not contain stem cells. Option C is incorrect because the trophoblast does not contain stem cells. Option D is incorrect because only the inner cell mass contains stem cells.
