**Core Concept**
The process being tested is the early division of a zygote, which is a fertilized egg cell, resulting in the formation of daughter cells. This process is a fundamental aspect of embryonic development and is crucial for the establishment of a viable embryo.

**Why the Correct Answer is Right**
During cleavage, the zygote undergoes a series of rapid cell divisions without significant growth, resulting in the formation of multiple cells from the original single cell. This process is characterized by the rapid and repeated division of the zygote, leading to the formation of blastomeres, which are the daughter cells formed during cleavage. The cleavage process is essential for the development of the embryo, as it allows for the establishment of a large number of cells that will eventually give rise to the various tissues and organs of the body.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because cleavage is not a type of cell differentiation, but rather a process of cell division.
* **Option B:** This option is incorrect because mitosis is the type of cell division that occurs during cleavage, but it is not the correct term for the process itself.
* **Option C:** This option is incorrect because embryogenesis is the broader process of development from a fertilized egg to a mature organism, but it does not specifically refer to the early division of the zygote.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that cleavage is a critical process in early embryonic development, and any disruption to this process can have significant consequences for the developing embryo.

**Correct Answer: C. Daughter cells formed from the cleavage of zygote are called blastomeres.**
