Ultraviolet radiations produce the photo oxidant

Options

A. `SO_(2)`
B. Flouride
C. CO
D. `O_(3)`

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which photo-oxidant is produced by ultraviolet (UV) radiations.

2. **Identifying the Options**: The options provided are:
- SO2 (Sulfur Dioxide)
- Fluoride
- CO (Carbon Monoxide)
- O3 (Ozone)

3. **Analyzing the Role of Ultraviolet Radiation**:
- Ultraviolet radiation from sunlight interacts with oxygen (O2) in the atmosphere.
- This interaction leads to a chemical reaction that results in the formation of ozone (O3).

4. **Formation of Ozone**:
- In the stratosphere, UV rays catalyze the polymerization of oxygen molecules (O2) to form ozone (O3).
- Ozone plays a crucial role in absorbing UV radiation, thus protecting the Earth's surface.

5. **Reviewing Other Options**:
- **SO2 (Sulfur Dioxide)**: Produced from the combustion of fossil fuels, not directly from UV radiation.
- **Fluoride**: Occurs naturally and is not produced by UV radiation.
- **CO (Carbon Monoxide)**: Also a product of fuel combustion, not related to UV radiation.

6. **Conclusion**: The correct answer to the question is O3 (Ozone), as it is the photo-oxidant produced by ultraviolet radiation.

### Final Answer:
The photo-oxidant produced by ultraviolet radiations is O3 (Ozone).
