<reasoning>

Analyze the description of meiosis

Meiosis is a specialized form of cell division that specifically produces gametes (sex cells like egg and sperm cells) with half the chromosome number of the parent cell. Thus, the best description among the choices is that it is the division of sex cells.

Analyze the description of mitosis

Mitosis is the process of nuclear division where replicated chromosomes are separated into two new nuclei. It is specifically the division of the chromosomes and the nucleus, distinct from cytokinesis (division of the cytoplasm) and general cell division.

Analyze the definition of cancer

Cancer is characterized by uncontrolled cell division. This occurs when the normal regulatory mechanisms of the cell cycle fail, meaning the cell cycle is no longer regulated.
