Answer: (C)

Verified step by step guidance

1. Understand the process of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells. It consists of two consecutive divisions: meiosis I and meiosis II.
2. Identify the starting cell: A primary spermatocyte is a diploid cell (2n) that undergoes meiosis to produce sperm cells. It contains the full set of chromosomes before division.
3. Follow the events of meiosis I: During meiosis I, homologous chromosomes are separated, resulting in two haploid secondary spermatocytes (n). Each secondary spermatocyte contains half the original chromosome number.
4. Follow the events of meiosis II: Each secondary spermatocyte undergoes meiosis II, where sister chromatids are separated. This results in four haploid spermatids (n), which will mature into sperm cells.
5. Conclude the process: A single primary spermatocyte ultimately produces four sperm cells after completing both stages of meiosis and maturation.
