Options

A. `(ii) 2500 mL, (iii) 4500 mL`
B. `(iii) 1200 mL, (iv) 2500 mL`
C. `(iv) 3500 mL, (i) 1200 mL`
D. `(i) 4500 mL, (ii) 3500 mL`

Explanation

To solve the question regarding the respiratory capacities and volumes of a normal human adult, we will match each respiratory capacity with its corresponding volume of air. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Identify Residual Volume (RV)**:
- **Definition**: The residual volume is the amount of air that remains in the lungs after a forceful expiration.
- **Volume**: 1200 mL
- **Match**: Residual Volume = 1200 mL

2. **Identify Vital Capacity (VC)**:
- **Definition**: Vital capacity is the maximum volume of air that can be inspired after a forceful expiration. It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume.
- **Volume**: 4500 mL
- **Match**: Vital Capacity = 4500 mL

3. **Identify Inspiratory Reserve Volume (IRV)**:
- **Definition**: Inspiratory reserve volume is the extra volume of air that can be inspired after a normal inspiration.
- **Volume**: 2500 mL
- **Match**: Inspiratory Reserve Volume = 2500 mL

4. **Identify Inspiratory Capacity (IC)**:
- **Definition**: Inspiratory capacity is the maximum volume of air that can be inspired after a normal expiration. It is the sum of tidal volume and inspiratory reserve volume.
- **Volume**: 3500 mL
- **Match**: Inspiratory Capacity = 3500 mL

### Summary of Matches:
- (i) Residual Volume = 1200 mL
- (ii) Vital Capacity = 4500 mL
- (iii) Inspiratory Reserve Volume = 2500 mL
- (iv) Inspiratory Capacity = 3500 mL

### Final Answer:
The correct matching of respiratory capacities and volumes is:
- Residual Volume (1200 mL)
- Vital Capacity (4500 mL)
- Inspiratory Reserve Volume (2500 mL)
- Inspiratory Capacity (3500 mL)
