The following are reformed during Telophase

Options

A. Nucleolus
B. Golgi complex
C. ER
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Mitosis Phases**: Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase. Each phase has specific events that occur.

2. **Identifying Changes in Prophase**: During prophase, several structures disassemble or disappear. These include:
- The nucleolus
- The Golgi complex
- The endoplasmic reticulum (ER)
- The nuclear membrane

3. **Analyzing Metaphase**: In metaphase, chromosomes align at the metaphase plate. There are no significant reformation of organelles during this phase.

4. **Observing Anaphase**: In anaphase, the sister chromatids are pulled apart toward opposite poles of the cell. Similar to metaphase, there is no reformation of organelles during this stage.

5. **Focusing on Telophase**: Telophase is the final stage of mitosis where the cell begins to re-establish its normal structures. During this phase:
- The nucleolus reforms.
- The Golgi complex reforms.
- The endoplasmic reticulum (ER) reforms.
- The nuclear membrane re-forms around the separated sets of chromosomes.

6. **Conclusion**: Since all the mentioned organelles (nucleolus, Golgi complex, and ER) reform during telophase, the correct answer to the question is "all."

**Final Answer**: All of the above (nucleolus, Golgi complex, ER) are reformed during telophase.
