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

Answer

To solve the problem of matching excretory organs with the corresponding animals, we will go through each excretory organ listed in Column I and identify the correct animal from Column II.

### Step-by-Step Solution:

1. **Identify the excretory organ: Nephridia**
- Nephridia are the excretory organs found in annelids, such as leeches.
- **Match:** Nephridia → (ii) Leech

2. **Identify the excretory organ: Malpighian tubules**
- Malpighian tubules are the excretory structures found in arthropods, specifically in insects like cockroaches.
- **Match:** Malpighian tubules → (v) Cockroach

3. **Identify the excretory organ: Protonephridia**
- Protonephridia are the excretory organs found in flatworms and some other invertebrates, but they are specifically associated with roundworms (Nematoda).
- **Match:** Protonephridia → (iv) Roundworms

4. **Identify the excretory organ: Kidneys**
- Kidneys are the excretory organs characteristic of vertebrates, including mammals. Sharks, being cartilaginous fish, also possess kidneys.
- **Match:** Kidneys → (iii) Shark

### Final Matches:
- A. Nephridia → (ii) Leech
- B. Malpighian tubules → (v) Cockroach
- C. Protonephridia → (iv) Roundworms
- D. Kidneys → (iii) Shark

### Correct Option:
Based on the matches, the correct option is:
- **Option 1:**
- A → (ii)
- B → (v)
- C → (iv)
- D → (iii)
