Answer: The correct answer is Mitosis.
Mitosis is a type of cell division in which parent cell is converted into two daughter cells having same number of chromosomes as that of the parent cell.
It is divided into the following stages-
1) Prophase- It is the first phase of mitosis in which condensation of chromosomes ( clearly visible chromosomes with sister chromatids) takes place and the nuclear membrane is disappeared.
2) Metaphase- It is the second phase in which chromosomes are aligned at the equatorial plate of the cell and they are anchored by microtubules from opposite poles.
3) Anaphase- It is the third phase in which each sister chromatid of the chromosome is pulled apart ( with the help of microtubules) towards the opposite pole.
4) Telophase- Chromosome decondensation takes place and nuclear membrane is formed so that two nuclei are visible now.
5) Cytokinesis- It is the last phase of mitosis in which division of cytoplasm takes place so that two daughter cells are produced having same number of chromosomes as their parent cell.
