Match the columns and find out the correct combination
`{:("A. Asthma "," 1. Recurring of bronchitis "),("B. Emphysema "," 2. Accumulation of WBCs in alveolus"),("C. Pneumonia "," 3. Allergy"):}`

Options

A. A - 3 B - 1 C - 2
B. A - 2 B - 1 C - 3
C. A - 3 B - 1 C - 3
D. A - 2 B - 3 C - 1

Answer

To solve the matching question, we need to analyze each condition and its corresponding description.

### Step-by-Step Solution:

1. **Identify the conditions:**
- A. Asthma
- B. Emphysema
- C. Pneumonia

2. **Analyze the descriptions:**
- 1. Recurring of bronchitis
- 2. Accumulation of WBCs in alveolus
- 3. Allergy

3. **Match each condition with its description:**
- **Asthma**: This condition is often triggered by allergies (like dust or pollen) which cause the airways to narrow. Therefore, we match **A (Asthma)** with **3 (Allergy)**.
- **Emphysema**: This condition is characterized by damage to the alveoli and is often associated with chronic bronchitis. It can be described as a recurring issue related to bronchitis. Thus, we match **B (Emphysema)** with **1 (Recurring of bronchitis)**.
- **Pneumonia**: This is an infection that leads to the accumulation of white blood cells (WBCs) in the alveoli, indicating an immune response to the infection. Hence, we match **C (Pneumonia)** with **2 (Accumulation of WBCs in alveolus)**.

4. **Final Matching:**
- A → 3 (Asthma → Allergy)
- B → 1 (Emphysema → Recurring of bronchitis)
- C → 2 (Pneumonia → Accumulation of WBCs in alveolus)

### Correct Combination:
- A → 3
- B → 1
- C → 2

### Conclusion:
The correct combination is:
- A: 3
- B: 1
- C: 2
