What is mitosis?

Explanation:
Mitotis is the division of a cell into two new cells by splitting its nucleus and distributing the chromosomes evenly. During mitosis the chromosomes are carefully separated into two new nuclei, and then cytokinesis usually follows to divide the cytoplasm, yielding two separate daughter cells. This makes the overall outcome the division of cells, which is why that option fits best. DNA replication happens earlier in the cell cycle (not during mitosis), movement of chromosomes occurs as part of mitosis but isn’t the whole process, and breaking down molecules isn’t involved in this division.
