The quality and number of chromosomes remain unchanged in.
A
Meiosis
B
Amitosis
C
Mitosis
D
All of these
Explanation: 

Detailed explanation-1: -In the mitosis two daughter cell formed, they are alike to parent cell in the number and type of chromosome. So due to mitosis, the number of chromosomes in the cell remains the same therefore the division occurred in the parent cell.

Detailed explanation-2: -The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation.

Detailed explanation-3: -In any given asexually reproducing species, the chromosome number is always the same. In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.

Detailed explanation-4: -„If there are too many or too few chromosomes, inside a cell, then there will be a corresponding increase or decrease in the amount of proteins that are made. This probably causes cell stress and leads to cellular damage“. In this way, the whole cellular system loses its balance.
