Answer:
Option 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.
Explanation:
Mitosis is a type of cell division in which a single parent cell is divided into two identical daughter cells. In mitosis, the parent cell is diploid i. e. double number of chromosomes. When replication of chromosome occurs, two identical copies of chromosome are made which is distributed to each daughter cell so the daughter cells are also diploid.
This type of cell division occurs in somatic cells or body cells.
