Which one contains haploid set of chromosomes

Options

A. Spermatogonium
B. Primary spermatocyte
C. secondary spermatocyte
D. primordial germ cell

Answer

**Step-by-Step Solution:**

1. **Understanding Haploid Cells:**
- A haploid cell is defined as a cell that contains a single set of chromosomes. This means that it has half the number of chromosomes compared to diploid cells, which contain two sets of chromosomes (one from each parent).

2. **Identifying Gametes:**
- In humans, gametes (sperm and egg cells) are examples of haploid cells. Each gamete contains 23 chromosomes, which is half the total number of chromosomes (46) found in diploid somatic cells.

3. **Analyzing the Options:**
- The question provides multiple options, and we need to determine which one represents a haploid set of chromosomes.
- It is important to identify which cells are haploid and which are diploid.

4. **Identifying Secondary Spermatocytes:**
- Among the options, secondary spermatocytes are specifically mentioned as haploid cells. They are formed during the process of meiosis in males and contain half the number of chromosomes (23 in humans).

5. **Conclusion:**
- Therefore, the correct answer to the question "Which one contains a haploid set of chromosomes?" is the secondary spermatocyte.

**Final Answer:**
- The correct option is **C: Secondary Spermatocyte**.
