Explanation

To solve the problem of matching the catalysts from Column I with the products from Column II, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Catalyst V₂O₅:**
- V₂O₅ (Vanadium pentoxide) is primarily used in the **Contact Process** for the production of sulfuric acid (H₂SO₄).
- **Match:** V₂O₅ → (iii) H₂SO₄.

2. **Identify the Catalyst TiCl₄/Al(Me)₃:**
- TiCl₄ combined with Al(Me)₃ forms the **Ziegler-Natta catalyst**, which is used for the polymerization of alkenes, specifically converting ethylene (ethene) into polyethylene.
- **Match:** TiCl₄/Al(Me)₃ → (i) Polyethylene.

3. **Identify the Catalyst PdCl₂:**
- PdCl₂ (Palladium(II) chloride) is used in the **Wacker Process**, which converts ethanol (C₂H₅OH) into acetaldehyde (CH₃CHO).
- **Match:** PdCl₂ → (ii) Ethanol.

4. **Identify the Catalyst Iron Oxide:**
- Iron oxide (Fe₂O₃) is used as a catalyst in the **Haber Process** for the synthesis of ammonia (NH₃) from nitrogen (N₂) and hydrogen (H₂).
- **Match:** Iron Oxide → (iv) NH₃.

### Final Matching:
- A (V₂O₅) → (iii) H₂SO₄
- B (TiCl₄/Al(Me)₃) → (i) Polyethylene
- C (PdCl₂) → (ii) Ethanol
- D (Iron Oxide) → (iv) NH₃

### Summary of Matches:
- A → (iii)
- B → (i)
- C → (ii)
- D → (iv)

### Conclusion:
The correct option that matches the catalysts with their respective products is option C:
- A3, B1, C2, D4.
