Options

A. Cuboidal Epithelium
B. Squamous Epithelium
C. Ciliated Epithelium
D. Colummar Epithelium

Answer

### Step-by-Step Solution:

1. **Understanding the Choroid**: The choroid is a layer of the eye located between the retina and the sclera. It plays a crucial role in providing nutrients and oxygen to the outer layers of the retina.

2. **Identifying the Type of Epithelium**: The question asks what type of epithelium lines the choroid. The correct answer is simple cuboidal epithelium.

3. **Justifying the Answer**: Simple cuboidal epithelium is a type of epithelial tissue that consists of a single layer of cube-shaped cells. This type of epithelium is found in various locations in the body, including the nephrons of the kidneys, seminiferous tubules, and the iris of the eye.

4. **Eliminating Incorrect Options**:
- **Squamous Epithelium**: Found in blood vessels and lining the coelom, but not in the choroid.
- **Ciliated Epithelium**: Present in the nephrons and auditory tube, but not in the choroid.
- **Columnar Epithelium**: Found in the stomach, intestine, and gallbladder, but not in the choroid.

5. **Final Conclusion**: Based on the information, the choroid of the eye is lined by simple cuboidal epithelium, making option number 1 the correct answer.
