Options

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

Answer

To solve the matching question, we will analyze each term in Column A and find the corresponding term in Column B.

### Step-by-Step Solution:

1. **Hermaphrodite**:
- Definition: An organism that has both male (testis) and female (ovary) reproductive organs.
- Match: This corresponds to option (ii) "Testis and ovary in the same animal".
- **Conclusion**: A → (ii)

2. **Direct Development**:
- Definition: A mode of development where the embryo develops directly into a mature individual without a larval stage.
- Match: This corresponds to option (iii) "Larval form absent".
- **Conclusion**: B → (iii)

3. **Chemoreceptor**:
- Definition: A sensory receptor that detects chemical substances in the environment.
- Match: This corresponds to option (iv) "Sense of chemical substances".
- **Conclusion**: C → (iv)

4. **Blood gland in earthworm**:
- Definition: The blood glands in earthworms are responsible for producing blood cells and hemoglobin.
- Match: This corresponds to option (i) "Produces blood cells and haemoglobin".
- **Conclusion**: D → (i)

### Final Matching:
- A → (ii)
- B → (iii)
- C → (iv)
- D → (i)

### Summary of the Correct Matches:
- A. Hermaphrodite → (ii) Testis and ovary in the same animal
- B. Direct development → (iii) Larval form absent
- C. Chemoreceptor → (iv) Sense of chemical substances
- D. Blood gland in earthworm → (i) Produces blood cells and haemoglobin
