Match the items in Column - I with those in Column - II and choose the correct option from the codes given below :
`{:(" Column-I "," Column-II "),("(a) Catalytic converter ","(i) Hospital waste "),("(b) Muffler ","(ii) " SO_(2)""),("(c) Incinerator","(iii) Noise"),("(d) Scrubber","(iv) CO"):}`

Options

A. `{:("(a)","(b)","(c)","(d)"),("(iii)","(iv)","(i)","(ii)"):}`
B. `{:("(a)","(b)","(c)","(d)"),("(iv)","(iii)","(ii)","(i)"):}`
C. `{:("(a)","(b)","(c)","(d)"),("(iv)","(i)","(iii)","(ii)"):}`
D. `{:("(a)","(b)","(c)","(d)"),("(iv)","(iii)","(i)","(ii)"):}`

Answer

To match the items in Column-I with those in Column-II, we can analyze each item in Column-I and determine what it corresponds to in Column-II based on their functions and applications.

### Step-by-Step Solution:

1. **Catalytic Converter (a)**:
- The catalytic converter is a device used in automobiles to reduce harmful emissions. It converts carbon monoxide (CO) into carbon dioxide (CO₂) and also reduces other harmful gases.
- **Match**: Catalytic Converter (a) → Carbon Monoxide (CO) (iv).

2. **Muffler (b)**:
- A muffler, also known as a silencer, is used to reduce noise produced by the exhaust of an internal combustion engine.
- **Match**: Muffler (b) → Noise (iii).

3. **Incinerator (c)**:
- An incinerator is a facility used for burning waste materials, particularly effective for hospital waste and hazardous materials, as it can destroy pathogens and toxins at high temperatures.
- **Match**: Incinerator (c) → Hospital Waste (i).

4. **Scrubber (d)**:
- A scrubber is a device used to remove pollutants, particularly sulfur dioxide (SO₂), from industrial exhaust gases.
- **Match**: Scrubber (d) → SO₂ (ii).

### Final Matches:
- (a) Catalytic Converter → (iv) CO
- (b) Muffler → (iii) Noise
- (c) Incinerator → (i) Hospital Waste
- (d) Scrubber → (ii) SO₂

### Correct Option:
Based on the matches:
- A → iv
- B → iii
- C → i
- D → ii

The correct option is **A4, B3, C1, D2**.
