Answer:
Meiosis.
Explanation:
Meiosis may be defined as the process of cell division in which a single parent cell divides into four daughter cells. This type of division occurs in the sex cells.
The meiosis division is also known as reduction division because the daughter cells contain the half number of chromosomes as compared with parent cell. The meiosis is divided into meiosis-I and meiosis-II.
Thus, the correct answer is option (C).

The answer is A. this is caused by a mutation in the beta
thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual.
The alpha subunit is normal in people with sickle cell disease. When sickle
hemoglobin releases oxygen in the peripheral tissues, the molecules tend to
stick together and form long chains or polymers. These rigid polymers distort
the cell and cause it to bend out of shape from
the normative disc shape.
