The process of cell division that creates genetic variety in cells is

cell fission

meiosis

mitosis

asexual reproduction

There are two ways that cells divide:  Mitosis and Meiosis. Our body cells, like our skin cells and liver cells and almost every cell in our body, divide using mitosis Our sex cells, on the other hand, divide using meiosis. During meiosis, the genes in our chromosomes switch all around, and change places with one another. This is called "crossing over." And it creates genetic variety. Answer is A. Meiosis.
