Options

A.
B.
C.
D.

Explanation

To answer the question "Which of the following epithelial tissues lines the stomach and intestine?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Epithelial Tissue**: Epithelial tissues are layers of cells that cover the surfaces of the body, both inside and out. They serve various functions, including protection, absorption, secretion, and sensation.

2. **Identify the Types of Epithelial Tissue**: There are several types of epithelial tissues, including:
- **Squamous Epithelium**: Thin and flat cells.
- **Cuboidal Epithelium**: Cube-shaped cells.
- **Columnar Epithelium**: Pillar-like or elongated cells.

3. **Focus on the Function and Location**: The stomach and intestines are involved in digestion and absorption. They require epithelial tissue that can facilitate these processes.

4. **Determine the Appropriate Epithelial Tissue**:
- **Squamous Epithelium** is not suitable for the stomach and intestine as it is too thin for absorption and secretion.
- **Cuboidal Epithelium** is typically found in glands and does not line the stomach or intestines.
- **Columnar Epithelium** is ideal for the stomach and intestines because it is designed for absorption and secretion. It can also have modifications, such as cilia, but the basic form is what lines these organs.

5. **Conclusion**: The epithelial tissue that lines the stomach and intestine is **Columnar Epithelium**.

### Final Answer:
The epithelial tissue that lines the stomach and intestine is **Columnar Epithelium**.
