C. October-November
D. December-January

Answer

To determine the months in which the ozone hole appears over the poles, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Ozone Layer**: The ozone layer is located in the stratosphere and protects the Earth from harmful ultraviolet (UV) radiation. It is crucial for life on Earth.

2. **Identifying the Ozone Hole**: The term "ozone hole" refers to a significant depletion of ozone in the stratosphere, particularly over the polar regions, especially Antarctica.

3. **Conditions for Ozone Depletion**: The formation of the ozone hole occurs under specific atmospheric conditions. These conditions include extremely low temperatures that lead to the formation of stratospheric polar clouds (PSCs).

4. **Timing of Ozone Hole Formation**: The ozone hole typically forms during the Southern Hemisphere's winter and spring months. This is primarily from the end of August through September.

5. **Conclusion**: Therefore, the months in which the ozone hole appears over the poles are **August to September**.

### Final Answer:
The ozone hole appears over the poles during the months of **August to September**.
