The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Telophase**: - Telophase is the final stage of cell division, which can occur during either mitosis or meiosis. It follows the anaphase and is characterized by significant changes in the cell. 2. **Nuclear Membrane Formation**: - During telophase, the nuclear membrane begins to reform around the separated sets of chromosomes. This is a crucial step as it marks the re-establishment of the nucleus in each daughter cell. 3. **Reappearance of the Nucleolus**: - Along with the nuclear membrane, the nucleolus, which is involved in ribosome production, also reappears during telophase. This indicates that the cell is preparing for its normal functions post-division. 4. **Disappearance of Astral Rays**: - Astral rays, which are part of the spindle apparatus that helps in the segregation of chromosomes, begin to disappear during telophase. This occurs because the chromosomes have already been separated and the cell is transitioning towards the end of division. 5. **Conclusion**: - All the mentioned events occur during telophase: the nuclear membrane is formed, the nucleolus appears, and the astral rays disappear. Therefore, the correct answer to the question is "all of the above". ### Final Answer: - The correct option is **D) all of the above**. ---
