Choose the correctly matched pair :

Options

A. Inner surface of bronchioles - Squamous epithelium
B. Inner lining of salivary ducts - Ciliated epithelium
C. Moist surface of Buccal cavity - Glandular epithelium
D. Tubular parts of nephrons - Cuboidal epithelium

Answer

To solve the question "Choose the correctly matched pair," we need to analyze each option provided and determine if the pair is correctly matched based on the type of epithelium present in each case.

### Step-by-Step Solution:

1. **Analyze Option 1: Inner Surface of Bronchioles**
- The option states that the inner surface of bronchioles is matched with squamous epithelium.
- **Evaluation**: This is incorrect. The inner surface of bronchioles is lined with ciliated epithelium, which helps in the movement of mucus and particles out of the respiratory tract.

2. **Analyze Option 2: Inner Lining of Salivary Duct**
- The option states that the inner lining of the salivary duct is matched with ciliated epithelium.
- **Evaluation**: This is also incorrect. The salivary duct is lined by compound epithelium, which is more suitable for the protective function in this area.

3. **Analyze Option 3: Moist Surface of Buccal Cavity**
- The option states that the moist surface of the buccal cavity is matched with glandular epithelium.
- **Evaluation**: This is incorrect as well. The buccal cavity is lined by stratified squamous epithelium, which is adapted for protection against abrasion.

4. **Analyze Option 4: Tubular Part of the Nephron**
- The option states that the tubular part of the nephron is matched with cuboidal epithelium.
- **Evaluation**: This is correct. The tubular part of the nephron, particularly the proximal convoluted tubule, is lined with cuboidal epithelium, which is involved in absorption and secretion.

### Conclusion:
The correctly matched pair is **Option 4: Tubular part of the nephron with cuboidal epithelium**.
