D. 4)`A rarr(v),(iv) B rarr (i),(ii)C rarr (v),(vi)`

Answer

To solve the matching question between Column-I and Column-II, we will analyze the characteristics of each group of animals listed in Column-I and match them with the appropriate descriptions in Column-II.

### Step-by-Step Solution:

1. **Identify the characteristics of Fish (Column-I A)**:
- Fish have a **2-chambered heart**.
- Fish exhibit **single circulation** (blood flows in one direction).

**Match**:
- A (Fish) → (v) 2-chambered heart
- A (Fish) → (iv) Single circulation

2. **Identify the characteristics of Amphibia (Column-I B)**:
- Amphibians have a **3-chambered heart**.
- Amphibians have **incomplete double circulation** (oxygenated and deoxygenated blood can mix in the heart).

**Match**:
- B (Amphibia) → (i) 3-chambered heart
- B (Amphibia) → (ii) Incomplete double circulation

3. **Identify the characteristics of Birds (Column-I C)**:
- Birds have a **4-chambered heart**.
- Birds exhibit **double circulation** (separate pathways for oxygenated and deoxygenated blood).

**Match**:
- C (Birds) → (iii) 4-chambered heart
- C (Birds) → (vi) Double circulation

### Final Matching:
- A (Fish) → (v) 2-chambered heart
- A (Fish) → (iv) Single circulation
- B (Amphibia) → (i) 3-chambered heart
- B (Amphibia) → (ii) Incomplete double circulation
- C (Birds) → (iii) 4-chambered heart
- C (Birds) → (vi) Double circulation

### Conclusion:
The correct matches are:
- A → (v) and (iv)
- B → (i) and (ii)
- C → (iii) and (vi)

Thus, the correct option is:
- A is 5 and 4
- B is 1 and 2
- C is 3 and 6
