Condensation of chromosomes is completed and can be observed clearly under microscope during

Options

A. Prophase
B. Metaphase
C. Anaphase
D. Telophase

Answer

To determine during which phase of cell division the condensation of chromosomes is completed and can be observed clearly under a microscope, we can analyze each phase of mitosis:

1. **Understanding the Phases of Mitosis**:
- Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase. Each phase has distinct characteristics regarding the state of chromosomes.

2. **Analyzing Prophase**:
- During prophase, chromosomes begin to condense and become visible. However, they are not yet fully condensed and clearly observable under a microscope. Thus, prophase is not the correct answer.

3. **Analyzing Metaphase**:
- In metaphase, chromosomes are fully condensed and aligned at the metaphase plate. This is the stage where they are most clearly visible under a microscope. Therefore, metaphase is a strong candidate for the correct answer.

4. **Analyzing Anaphase**:
- Anaphase is characterized by the separation of sister chromatids, which move towards opposite poles of the cell. While the chromatids are still visible, this phase is not primarily focused on the condensation of chromosomes. Thus, anaphase is not the correct answer.

5. **Analyzing Telophase**:
- Telophase is the final phase of mitosis where the chromosomes begin to de-condense and the nuclear envelope reforms. Since the chromosomes are unwinding, this phase cannot be the correct answer for when condensation is completed.

6. **Conclusion**:
- Based on the analysis, the phase during which the condensation of chromosomes is completed and can be observed clearly under a microscope is **metaphase**.

### Final Answer:
Metaphase
