Answer:
The correct answer would be A. mitosis.
Mitosis is a type of cell division which results in the formation of two daughter cells each containing same DNA as its parent cell.
It usually takes place in somatic cells of eukaryotic organisms.
It helps in growth and repair of cells or tissues in multi-cellular organisms.
In contrast, meiosis takes place in germ cells to produce haploid gametes. Gametes contains half the number of chromosomes present in parent cell. In addition, crossing over takes place in meiosis which results in the genetic variation.
