Match column I with column II and select the correct option from the given codes.
`{:("Column I", "Column II"),("Nitrates", (i)"Primary pollutant"),("E-Wastes", (ii) "Minamata disease"),("Mercury", (iii)"Secondary pollutant"),("DDT", (iv) "Blue-baby syndrome"),("PAN", (v)"Electronic wastes"):}`

Options

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

Answer

To solve the matching question, we need to pair the items in Column I with their corresponding items in Column II based on the information provided. Here’s a step-by-step breakdown:

### Step 1: Analyze Nitrates
- **Nitrates** are known to cause **blue baby syndrome** (methemoglobinemia), which occurs when infants consume water with high nitrate levels.
- **Match:** Nitrates → (iv) Blue-baby syndrome

### Step 2: Analyze E-Wastes
- **E-Wastes** refer to **electronic wastes** such as discarded computers, laptops, and other electronic devices.
- **Match:** E-Wastes → (v) Electronic wastes

### Step 3: Analyze Mercury
- **Mercury** is associated with **Minamata disease**, which was first reported in 1952 due to mercury contamination in fish.
- **Match:** Mercury → (ii) Minamata disease

### Step 4: Analyze DDT
- **DDT** (Dichloro-Diphenyl-Trichloroethane) is a pesticide and is classified as a **primary pollutant** because it is directly released into the environment.
- **Match:** DDT → (i) Primary pollutant

### Step 5: Analyze PAN
- **PAN** (Peroxyacyl nitrate) is considered a **secondary pollutant** because it forms in the atmosphere from the reaction of primary pollutants.
- **Match:** PAN → (iii) Secondary pollutant

### Summary of Matches:
- Nitrates → (iv) Blue-baby syndrome
- E-Wastes → (v) Electronic wastes
- Mercury → (ii) Minamata disease
- DDT → (i) Primary pollutant
- PAN → (iii) Secondary pollutant

### Final Answer:
The correct option that matches all the items is Option 2.
