Mitosis is a cell division of a single cell into two identical daughter cells. So, at the beginning of mitosis, there is only one cell. It will undergo different stages of mitosis (prophase, metaphase, anaphase, telophase and cytokinesis) which will result in the formation of two daughter cells that are identical to the mother cells.

Answer: mitosis
Explanation:
Mitosis is the process when a parent cell is divided, and two daughter cells are found after the process. This question says that when the parent cell is split, two daughter cells are the result. This is mitosis, so the answer is D.
