Which pollutants are responsible for bronchitis?

Options

A. `O_2,CO_2`
B. ` CO,CO_2`
C. ` SO_2,NO_2`
D. ` Cl_2,H_2S`

Answer

**Step-by-Step Solution:**

1. **Understanding Bronchitis**: Begin by defining bronchitis. Bronchitis is a type of respiratory inflammation that affects the lungs and bronchial area. It can be caused by infections or irritants.

2. **Identifying the Cause**: Recognize that bronchitis is often linked to pollution, which is caused by various pollutants in the environment.

3. **Listing Potential Pollutants**: The question provides several options for pollutants. We need to analyze which of these are known to contribute to bronchitis.

4. **Analyzing Each Option**:
- **Oxygen and Carbon Dioxide**: These are not pollutants that cause bronchitis.
- **Carbon Monoxide and Carbon Dioxide**: While carbon monoxide is harmful, it is not primarily linked to bronchitis.
- **Sulfur Dioxide and Nitrogen Dioxide**: Both of these are known to irritate the respiratory system and are linked to bronchitis.
- **Chlorine Gas and Hydrogen Dioxide**: Chlorine gas can be harmful, but hydrogen dioxide (water) is not a pollutant.

5. **Conclusion**: Based on the analysis, the pollutants responsible for bronchitis are **Sulfur Dioxide (SO2)** and **Nitrogen Dioxide (NO2)**.

**Final Answer**: Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2) are the pollutants responsible for bronchitis.
