Options

B. Iris
C. Eye lens
D. Cornea

Answer

To determine which part of the eye protects the inner part, we need to analyze the functions of the four options provided: sclera, iris, eye lens, and cornea.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are sclera, iris, eye lens, and cornea.

2. **Understand the Function of Each Part**:
- **Sclera**: The sclera is the white outer layer of the eyeball. Its primary function is to protect the inner parts of the eye, including the retina.
- **Iris**: The iris is the colored part of the eye that controls the size of the pupil, regulating the amount of light that enters the eye. It does not provide protection.
- **Eye Lens**: The eye lens is a transparent structure that helps focus light onto the retina. While important for vision, it does not serve a protective function.
- **Cornea**: The cornea is the clear front part of the eye that covers the iris and pupil. It helps to focus light but is not primarily responsible for protecting the inner parts of the eye.

3. **Determine the Correct Answer**: Based on the functions analyzed, the **sclera** is the part that protects the inner parts of the eye.

4. **Conclusion**: Therefore, the correct answer to the question "Which of these protects the inner part of the eye?" is the **sclera**.

### Final Answer:
The sclera protects the inner part of the eye.
