The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Cell Division:** Cell division is a process where a single cell divides to produce two daughter cells. This involves the division of the cell's genetic material, which can occur through mitosis or meiosis. 2. **Stages of Cell Division:** Mitosis and meiosis each have distinct stages: - Prophase - Metaphase - Anaphase - Telophase 3. **Identifying Interphase:** Interphase is the phase where the cell grows and prepares for division, but no actual division of genetic material occurs during this phase. Therefore, it is not relevant for counting chromosomes. 4. **Focusing on Metaphase:** During metaphase, chromosomes become highly condensed and are aligned at the equatorial plane of the cell. This alignment makes them distinguishable and easier to count. 5. **Conclusion:** The best stage to count the number of chromosomes is during metaphase, as the chromosomes are most visible and organized at this point. **Final Answer:** The number of chromosomes is best counted during the **metaphase** stage of cell division. ---
