Which one is wrongly matched

Options

A. Squamous epithelium - Skin of Frog
B. Columnar epithelium - Peritoneum of body cavity
C. Ciliated epithelium - Bronchioles
D. Stratified cuboidal epithelium - Oesophagus.

Answer

### Step-by-Step Text Solution

1. **Understanding the Question**: The question asks which of the given pairs of epithelial types and their respective locations is incorrectly matched.

2. **Analyzing the Options**:
- **Option A**: Squamous epithelium, skin of frog.
- **Option B**: Columnar epithelium, peritoneum of body cavity.
- **Option C**: Ciliated epithelium, bronchioles.
- **Option D**: Stratified cuboidal epithelium, esophagus.

3. **Evaluating Each Option**:
- **Option A**: The outer layer of the skin of a frog is indeed made up of simple squamous epithelium. This option is **correctly matched**.
- **Option B**: The peritoneum of the body cavity is lined with simple squamous epithelium, not columnar epithelium. This option is **incorrectly matched**.
- **Option C**: The walls of bronchioles contain ciliated epithelium, which is correctly matched as they have ciliated or non-ciliated cuboidal epithelium. This option is **correctly matched**.
- **Option D**: The esophagus is lined by stratified squamous epithelium, not cuboidal epithelium. This option is also **incorrectly matched**.

4. **Identifying the Wrong Match**: The only option that is clearly identified as incorrectly matched is **Option B**: Columnar epithelium, peritoneum of body cavity.

5. **Conclusion**: The answer to the question is that the wrongly matched pair is **Columnar epithelium, peritoneum of body cavity**.
