C. glass sheet
D. wood top covered with cloth

Answer

To solve the question about the table top that allows two students to see their own and each other's images, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Scenario**: Two students are sitting across a table and looking down at its top surface. They can see their own images and each other's images.

2. **Identify the Requirement for Reflection**: For the students to see their images, the surface of the table must be reflective. This means it needs to reflect light effectively.

3. **Evaluate the Options**: We need to consider the materials mentioned in the options:
- **Unpolished Wood**: This surface is rough and does not reflect light well. Therefore, it would not create clear images.
- **Glass Sheet**: Glass is a smooth and reflective surface. It can reflect light effectively, allowing the students to see their images.
- **Other Options (not specified)**: If there are other options like cloth or rough materials, they would also not provide a clear reflection.

4. **Conclusion**: Since the glass sheet is the only material that can reflect light properly and allow the students to see their images, it is the correct answer.

5. **Final Answer**: The table top is likely to be made of a **glass sheet**.
