The right answer is A.
During the cell cycle, the amount of DNA in the nucleus varies: it doubles during interphase, allowing the daughter cells to receive an amount equal to that initially present in the mother cell. During mitosis, the daughter cells thus receive the same number of chromosomes, which is equal to that of the mother cell. Mitosis is a consistent mode of reproduction. The number of chromosomes, which is characteristic of the species (46 in the human species, 23 pairs), is therefore kept constant during successive cell cycles.
