Electrostatic precipitators are extensively employed to control

Options

A. water pollution
B. air pollution
C. radioactive pollution
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding Electrostatic Precipitators**: Electrostatic precipitators are devices designed to remove particulate matter from the air. They work by charging particles and then collecting them on oppositely charged plates.

2. **Identifying the Type of Pollution**: The question asks what type of pollution electrostatic precipitators are used to control. The options given are water pollution, air pollution, radioactive pollution, or none of these.

3. **Analyzing the Function of Electrostatic Precipitators**: These devices are specifically effective in removing particulate matter, which typically includes dust, smoke, and other airborne particles. The size of the particles they can remove ranges from 5 to 20 micrometers.

4. **Conclusion**: Since electrostatic precipitators are designed to remove particulate matter from the air, they are extensively employed to control air pollution. They are not used for water pollution or radioactive pollution.

5. **Final Answer**: Therefore, the correct answer is **air pollution**.
