Options

A. pupil
B. iris
C. cornea
D. eye lens

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which part of the eye controls the amount of light entering it.

2. **Understanding Eye Anatomy**: To answer the question, we need to understand the basic anatomy of the eye. The main components involved in controlling light entry are the iris, pupil, and lens.

3. **Define the Iris**: The iris is the colored part of the eye that surrounds the pupil. It has muscles that can contract or expand to adjust the size of the pupil.

4. **Define the Pupil**: The pupil is the opening in the center of the iris. It allows light to enter the eye. The size of the pupil changes based on the amount of light in the environment.

5. **Function of the Iris**: When there is bright light, the iris contracts, making the pupil smaller to reduce the amount of light entering the eye. Conversely, in dim light, the iris expands, making the pupil larger to allow more light in.

6. **Conclusion**: Based on the functions of these parts, the iris is responsible for controlling the amount of light that enters the eye by adjusting the size of the pupil.

7. **Final Answer**: Therefore, the correct answer to the question is that the amount of light entering our eye gets controlled by the **iris**.
