The right answer is mitosis.
Mitosis refers to the chromosomal events of eukaryotic cell division. This is a nonsexual / asexual duplication (unlike meiosis).
It also refers to a very particular stage of the eukaryotic cell cycle, called the "cell cycle", which is the stage of duplication of each chromosome of the mother cell and of their equal distribution in each of the two daughter cells.
Mitosis allows the formation of two daughter cells strictly identical genetically to the mother cell.
