It should be natural selection since there is no external influence implied. (like environment or genetic mutations.)
the answer is C, the division of one cell into two identical cells :3
Interphase in the cell cycle encompasses the G1, S, and G2 phases, as it shows the period of growth and DNA replication that a cell must go through to prepare for mitosis. Cell division, which occurs during the M phase, is the only portion of the cell cycle that is not included in interphase.
