C. a-iv,b-i,c-ii,d-iii,e-v
D. a-ii,b-iii,c-i,d-iv,e-v

Answer

To solve the question of matching the vitamins with their respective functions, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Retinol**:
- Retinol is known as Vitamin A. Its primary function is related to the maintenance of epithelial tissues.
- **Match**: Retinol (a) → Essential for maintenance of epithelial tissue (iii).

2. **Identify Tocopherol**:
- Tocopherol is known as Vitamin E. It acts as an antioxidant and inhibits the oxidation of unsaturated fatty acids.
- **Match**: Tocopherol (b) → Inhibits oxidation of unsaturated fatty acids (i).

3. **Identify Calciferol**:
- Calciferol refers to Vitamin D. Its main role is in the absorption of calcium and phosphorus in the body.
- **Match**: Calciferol (c) → Absorption of Ca²⁺ (ii).

4. **Identify Menadione**:
- Menadione is known as Vitamin K. It is essential for blood clotting as it helps in the synthesis of clotting factors.
- **Match**: Menadione (d) → Helps in clotting of blood (iv).

5. **Identify Ascorbic Acid**:
- Ascorbic acid is Vitamin C. It is required for amino acid metabolism and is involved in various body functions including tissue repair.
- **Match**: Ascorbic acid (e) → Required for amino acid metabolism (v).

### Final Matches:
- a → iii (Retinol → Essential for maintenance of epithelial tissue)
- b → i (Tocopherol → Inhibits oxidation of unsaturated fatty acids)
- c → ii (Calciferol → Absorption of Ca²⁺)
- d → iv (Menadione → Helps in clotting of blood)
- e → v (Ascorbic acid → Required for amino acid metabolism)

### Conclusion:
The correct matches are:
- a - iii
- b - i
- c - ii
- d - iv
- e - v
