The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Cell Cycle**: The cell cycle consists of several phases, including interphase, mitotic phase (mitosis), and cytokinesis. Each phase has distinct functions and durations. 2. **Identifying the Phases**: - **Interphase**: This is the phase where the cell prepares for division. It includes growth (G1 phase), DNA synthesis (S phase), and preparation for mitosis (G2 phase). - **Mitotic Phase**: This is when the cell actually divides. It includes prophase, metaphase, anaphase, and telophase. - **Cytokinesis**: This is the final step of cell division, where the cytoplasm divides, resulting in two daughter cells. - **Meiotic Phase**: This is specific to the formation of gametes and is not part of the typical cell cycle in somatic cells. 3. **Duration of Each Phase**: - Interphase is the longest phase of the cell cycle, typically occupying about 90% of the total time. - The mitotic phase and cytokinesis take significantly less time, usually around 1 hour in a 24-hour cell cycle. 4. **Conclusion**: Since interphase occupies the maximum part of the cell cycle, the correct answer to the question is **Interphase (Option C)**. ### Final Answer: The phase that occupies the maximum part of the cell cycle is **Interphase (Option C)**. ---
