What is mitosis in a living cell?

a) the separation of the genetic material of a cell into two completely identical sets, one for each of the daughter cells created during cell division

b) the creation of two daughter cells with half the number of chromosomes that the parent cell has by the process of cell division

c)the creation of a larger amount of cytoplasmic material that can then be split among the daughter cells of a parent cell

d)the separation of existing genetic material by splitting chromatids at the centromere to create two similar nuclei in another cell​
