Answer

To solve the question of matching animals with their respective excretory organs, we will analyze each animal listed in Column-I and identify the correct excretory organ from Column-II.

### Step-by-Step Solution:

1. **Identify the excretory organ for Fasciola:**
- Fasciola, commonly known as the liver fluke, has an excretory system that includes **protonephridia**.
- **Match:** A (Fasciola) → iii (Protonephridia)

2. **Identify the excretory organ for Hirudinaria:**
- Hirudinaria, known as the medicinal leech, possesses **nephridia** as its excretory organ.
- **Match:** B (Hirudinaria) → i (Nephridia)

3. **Identify the excretory organ for Balanoglossus:**
- Balanoglossus, a member of the phylum Hemichordata, has a **proboscis gland** as its excretory organ.
- **Match:** C (Balanoglossus) → iv (Proboscis gland)

4. **Identify the excretory organ for Laccifer:**
- Laccifer, a type of lac insect, belongs to the phylum Arthropoda and has **Malpighian tubules** for excretion.
- **Match:** D (Laccifer) → ii (Malpighian tubules)

### Summary of Matches:
- A → iii (Fasciola → Protonephridia)
- B → i (Hirudinaria → Nephridia)
- C → iv (Balanoglossus → Proboscis gland)
- D → ii (Laccifer → Malpighian tubules)

### Final Matching:
- A (Fasciola) → iii (Protonephridia)
- B (Hirudinaria) → i (Nephridia)
- C (Balanoglossus) → iv (Proboscis gland)
- D (Laccifer) → ii (Malpighian tubules)

### Correct Option:
Based on the matches, the correct option is **3, 1, 4, 2**.
