Options

A. Molina and rowland
B. Farmanet al
C. Augus
D. molina and molina

Answer

**Step-by-Step Solution:**

1. **Understanding the Ozone Layer**: The ozone layer is located in the stratosphere, approximately 15 to 30 kilometers above the Earth's surface. It plays a crucial role in protecting the Earth from harmful ultraviolet (UV) radiation.

2. **Identifying the Problem**: The question asks who first detected the ozone hole over Antarctica. This is a specific event related to the depletion of the ozone layer.

3. **Recognizing Key Scientists**: The scientists who are often associated with the discovery of ozone depletion due to chlorofluorocarbons (CFCs) are Rowland and Molina. They demonstrated how CFCs could lead to ozone layer degradation.

4. **Finding the Correct Answer**: However, the detection of the ozone hole itself over Antarctica was first reported by a group of scientists including Furman, Gardiner, and Shanklin in the 1980s. This is a distinct event from the general understanding of ozone depletion.

5. **Conclusion**: Based on the information, the correct answer to the question is that the ozone hole over Antarctica was first detected by Furman et al.

**Final Answer**: The ozone hole over Antarctica was first detected by Furman et al.
