Ultraviolet rays in sunlight cause a reaction that produces the pollutant

Options

A. CO pollution
B. `CH_(4)`
C. `SO_(2)`
D. `O_(3)`

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the pollutant produced as a result of a reaction caused by ultraviolet rays in sunlight.

2. **Identifying the Reaction**: Ultraviolet rays can initiate chemical reactions in the atmosphere. One of the significant reactions involves the formation of secondary pollutants from primary pollutants.

3. **Recognizing the Pollutants**: The primary pollutants include nitrogen oxides (NOx) and volatile organic compounds (VOCs). When these substances react in the presence of sunlight (UV rays), they form secondary pollutants.

4. **Identifying the Secondary Pollutant**: One of the notable secondary pollutants formed from this reaction is Peroxyacetyl Nitrate (PAN). PAN is known to damage chloroplasts in plants, reducing photosynthetic efficiency.

5. **Conclusion**: Therefore, the pollutant produced due to the reaction of ultraviolet rays in sunlight is Peroxyacetyl Nitrate (PAN).

### Final Answer:
The pollutant produced by the reaction of ultraviolet rays in sunlight is Peroxyacetyl Nitrate (PAN).
