Match column I with column II and select the correct option from the given codes.
`{:("Column I", "Column II"),("Catalytic converter", (i)"Used in industries and power plants"),("Electrostatic precipitator", (ii) "Used in automobiles"),("Earmuffs", (iii)"High noise level"),("Land fils", (iv) "Solid wastes"):}`

Options

A. A-(i), B-(ii), C-(iii), D-(iv)
B. A-(ii), B-(i), C-(iii), D-(iv)
C. A-(iv), B-(iii), C-(ii),D-(i)
D. A-(iii),B-(ii), C-(iv), D-(i)

Answer

To solve the question, we need to match the items in Column I with their correct descriptions in Column II. Let's go through each item step by step.

### Step-by-Step Solution:

1. **Catalytic Converter**:
- A catalytic converter is a device used in automobiles. Its main function is to convert harmful gases from the engine's exhaust into less harmful emissions. It primarily converts unburnt hydrocarbons into carbon dioxide and water.
- **Match**: (ii) "Used in automobiles"

2. **Electrostatic Precipitator**:
- An electrostatic precipitator is an air pollution control device used in industries and power plants. It removes particulate matter from exhaust gases by applying electrostatic charge to the particles, allowing them to be collected.
- **Match**: (i) "Used in industries and power plants"

3. **Earmuffs**:
- Earmuffs are protective gear designed to cover the ears and protect them from high noise levels. They are commonly used in environments where noise pollution is a concern.
- **Match**: (iii) "High noise level"

4. **Landfills**:
- Landfills are sites for the disposal of solid waste. They are engineered to manage waste in a way that minimizes environmental impact.
- **Match**: (iv) "Solid wastes"

### Final Matches:
- Catalytic Converter → (ii) "Used in automobiles"
- Electrostatic Precipitator → (i) "Used in industries and power plants"
- Earmuffs → (iii) "High noise level"
- Landfills → (iv) "Solid wastes"

### Correct Option:
Based on the matches, the correct option is **B** or **2**.
