The correct option is B.

Explanation of the correct option:

2. The zygote stage of human and another animal embryonic development is brief, followed by cleavage when the single cell is subdivided into smaller cells.

Explanation of the incorrect options:

Option A:

1. The placenta is a fetal organ that is mainly temporarily developed in females.
2. It develops from the blastocyst shortly after fertilization.
3. The placenta assumes a totally urgent and fundamental part during the nine months of pregnancy.

Option C:

1. A morula is a solid mass of blastomeres that forms when a zygote, or fertilized egg, is cleaved into many pieces.
2. It is typically formed by species whose eggs have minimal yolk and, as a result, undergo complete cleavage.

Final answer:

The technical term for the fertilized egg is the zygote.
