The correct answer is:
**B mitosis - cytokinesis - cell differentiation**
Once the fertilized egg (zygote) is formed, it undergoes a series of mitotic divisions (cleavage) to produce multiple cells. This process includes cytokinesis, which is the division of the cytoplasm. Eventually, these cells undergo differentiation to develop into various cell types, leading to the formation of tissues and organs. Meiosis occurs before fertilization during the formation of the gametes, so it is not part of the developmental process following fertilization.
