I know it is meiosis and not mitosis, so I'm like 99% sure that it is A.
I think this because the 23 chromosomes then combine with the 23 chromosomes from the female to make 46.
So I'm pretty sure that it is A.

Answer:

A.One diploid cell, with 46 chromosomes, undergoes meiosis to form four haploid sperm cells, with 23 chromosomes each.

Explanation:

The diploid primary spermatocytes (2n=46) undergo meiosis I and forms two haploid secondary spermatocytes (n=23). The secondary spermatocytes undergo meiosis II and form total four sperm cells (n=23). Since the sperm cells are product of meiosis, they are haploid and each sperm cell have 23 chromosomes.
