Match column I with column II and select the correct option from the codes given below. `{:(,"Column I",,"Column II"),(A.,"TV + ERV",(i),expiratory capacity),(B.,"RV + ERV + TV + IRV",(ii),"Total Lung Capacity"),(C.,"ERV + RV",(iii),"Functional Residual Capacity"):}`.

Options

A. a) `A-(i), B-(ii), C-(iii)`
B. b) `A-(iii), B-(i), C-(ii)`
C. c) `A-(iii), B-(ii), C-(i)`
D. d) `A-(ii), B-(iii), C-(i)`

Answer

To solve the problem, we need to match the items in Column I with their corresponding definitions in Column II. Let's break it down step by step:

### Step 1: Identify the components in Column I
1. **TV + ERV**: This refers to the combination of Tidal Volume (TV) and Expiratory Reserve Volume (ERV).
2. **RV + ERV + TV + IRV**: This refers to the combination of Residual Volume (RV), Expiratory Reserve Volume (ERV), Tidal Volume (TV), and Inspiratory Reserve Volume (IRV).
3. **ERV + RV**: This refers to the combination of Expiratory Reserve Volume (ERV) and Residual Volume (RV).

### Step 2: Match each component with the correct definition in Column II
1. **TV + ERV**:
- This combination represents the maximum volume of air that can be expired after a normal tidal inspiration, which is known as **Expiratory Capacity**.
- **Match**: A → (i) Expiratory Capacity

2. **RV + ERV + TV + IRV**:
- This combination represents the total volume of air that the lungs can hold, known as **Total Lung Capacity**.
- **Match**: B → (ii) Total Lung Capacity

3. **ERV + RV**:
- This combination represents the volume of air remaining in the lungs after normal tidal expiration, known as **Functional Residual Capacity**.
- **Match**: C → (iii) Functional Residual Capacity

### Step 3: Compile the matches
- A → (i) Expiratory Capacity
- B → (ii) Total Lung Capacity
- C → (iii) Functional Residual Capacity

### Final Answer
The correct matches are:
- A → (i)
- B → (ii)
- C → (iii)
