Explanation:
Answer: The correct answer is D) The number of chromosomes remains the same in mitosis and is reduced by half in meiosis.
Explanation-
Mitosis and meiosis are the two forms of cell division. Mitosis occurs in all the living organisms. In mitosis, cell divides into two daughter, each having equal number of chromosomes with that of the parental cell. It is also a process of asexual reproduction.
Whereas, meiosis typically occurs in sexually reproducing organisms during gamete formation. In this process, the number of chromosomes are reduced to half as the homologous chromosomes are separated.
Thus, the number of chromosomes remains the same in mitosis and it is reduced by half in meiosis.
