`{:(" Column-I "," Column-II "),("a) Pyrolysis ","i) Methimoglobinemia "),("b) Carbon monoxide ","ii) Arsenic "),("c) Blue baby ","iii) Asphyxia "),("d) Black foot disease ","iv) Disposal of hospital waste "):}`

Options

A. a-(iv), b-(i), c-(ii), d-(iii)
B. a-(i), b-(iii), c-(iv), d-(ii)
C. a-(iv), b-(iii), c-(i), d-(ii)
D. a-(iv), b-(iii), c-(ii), d-(i)

Answer

To solve the matching question, we will analyze each item in Column-I and find its corresponding match in Column-II based on the definitions and associations provided in the video transcript.

### Step-by-step Solution:

1. **Identify Pyrolysis**:
- Pyrolysis is a thermal decomposition method used for waste disposal, particularly hospital waste.
- **Match**: a) Pyrolysis → iv) Disposal of hospital waste

2. **Identify Carbon Monoxide**:
- Carbon monoxide is a toxic gas that can lead to asphyxia, a condition where the body is deprived of oxygen, causing difficulty in breathing.
- **Match**: b) Carbon monoxide → iii) Asphyxia

3. **Identify Blue Baby Syndrome**:
- Blue baby syndrome is caused by nitrate poisoning, which leads to the production of methhemoglobin in the blood, resulting in methhemoglobinemia.
- **Match**: c) Blue baby → i) Methimoglobinemia

4. **Identify Black Foot Disease**:
- Black foot disease is associated with exposure to arsenic, often through contaminated drinking water.
- **Match**: d) Black foot disease → ii) Arsenic

### Final Matches:
- a) Pyrolysis → iv) Disposal of hospital waste
- b) Carbon monoxide → iii) Asphyxia
- c) Blue baby → i) Methimoglobinemia
- d) Black foot disease → ii) Arsenic

### Answer Summary:
The correct matches are:
- a) → iv
- b) → iii
- c) → i
- d) → ii
