D. d) `A-(iii), B-(i), C-(ii), (v), D-(vi), (vii), E-(iv)`

Answer

To solve the matching question, we will analyze each item in Column I and find the appropriate match in Column II.

### Step-by-Step Solution:

1. **A. Hemoglobin**:
- Hemoglobin is a protein in red blood cells that binds to carbon dioxide. The term "Carbomino-" refers to the compound formed when carbon dioxide binds to hemoglobin.
- **Match**: (iv) Carbon dioxide.

2. **B. Diaphragm**:
- The diaphragm is a muscle that plays a crucial role in the process of breathing. When it contracts, it causes inspiration (inhalation) by increasing the volume of the thoracic cavity.
- **Match**: (i) Inspiration.

3. **C. Larynx**:
- The larynx is an organ located in the throat that contains the vocal cords. It is also involved in the passage of air and protects the trachea against food aspiration.
- **Match**: (v) Cartilages.

4. **D. Pons Varolii**:
- The pons is part of the brainstem and contains the pneumotaxic center, which regulates the rhythm of breathing by inhibiting inspiration.
- **Match**: (vi) Pneumotaxic centre.

5. **E. Chloride shift**:
- The chloride shift refers to the process where bicarbonate ions (HCO3-) move out of red blood cells (RBCs) and chloride ions (Cl-) move in to maintain electrical neutrality. This process occurs in the context of gas exchange in the blood.
- **Match**: (ii) Hamburger's phenomenon.

### Final Matches:
- A - (iv) Carbon dioxide
- B - (i) Inspiration
- C - (v) Cartilages
- D - (vi) Pneumotaxic centre
- E - (ii) Hamburger's phenomenon

### Correct Option Code:
The correct option code based on the matches is:
- A - iv
- B - i
- C - v
- D - vi
- E - ii
