C. 3) `A-(ii),B-(i),C-(v),D-(iii)`
D. 4) `A-(iii),B-(i),C-(v),D-(ii)`

Answer

To solve the matching question, we need to pair each enzyme from Column I with its correct characteristic or activity from Column II. Here’s the step-by-step solution:

### Step 1: Identify the characteristics of each enzyme

1. **Taq DNA polymerase (A)**: This enzyme is known for its stability at high temperatures, specifically above 90°C, which is essential for its role in the polymerase chain reaction (PCR).

- **Match**: A - (iii) "Stable above 90°C"

2. **Exonuclease (B)**: This enzyme functions to cleave nucleotides from the ends of linear DNA molecules.

- **Match**: B - (i) "Cleaves the ends of linear DNA"

3. **Protease (C)**: Proteases are enzymes that degrade proteins by breaking down peptide bonds.

- **Match**: C - (v) "Degradation of proteins"

4. **Chitinase (D)**: Chitinase breaks down chitin, which is a component of the fungal cell wall.

- **Match**: D - (ii) "Breakdown of fungal cell wall"

### Step 2: Compile the matches

Now we compile the matches:
- A matches with (iii)
- B matches with (i)
- C matches with (v)
- D matches with (ii)

### Step 3: Write down the final matches in code form

Based on the matches we have:
- A - (iii)
- B - (i)
- C - (v)
- D - (ii)

### Step 4: Identify the correct answer option

Now, we need to find the option that correctly represents these matches:
1) A - (iii), B - (iv), C - (i), D - (ii) → Incorrect
2) A - (iv), B - (iii), C - (i), D - (ii) → Incorrect
3) A - (ii), B - (i), C - (v), D - (iii) → Incorrect
4) A - (iii), B - (i), C - (v), D - (ii) → Correct

### Final Answer

The correct answer is **Option 4**: A - (iii), B - (i), C - (v), D - (ii).
