Answer:a. mitosis
Explanation: mitosis is a type of cell division found in somatic cells.
The daughter cells contains the same number of chromosomes as the parent cell.
Mitosis involves four stages namely;prophase, metaphase, anaphase,telophase.
There is also an interphase,of normal functioning of the cells.
Mitosis is important in asexual reproduction , regeneration and replacement of lost cells.
It also causes growth in organisms.
Unlike meiosis , crossing over does not occur in mitosis thus there is no variation in daughter cells
