C. pupil
D. retina

Answer

To solve the question regarding where the human eye forms the image of an object, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Eye**:
- The human eye consists of several important parts: the cornea, iris, pupil, lens, and retina. Each part has a specific function in the process of vision.

2. **Identifying the Role of Each Part**:
- **Cornea**: This is the outermost layer of the eye that helps to focus light. However, it does not form the image.
- **Iris**: This part controls the amount of light that enters the eye by adjusting the size of the pupil. It does not form the image either.
- **Pupil**: The pupil is the opening in the center of the iris through which light enters the eye. It is not responsible for image formation.
- **Lens**: The lens focuses light onto the retina but does not form the final image.

3. **Identifying the Image Formation Location**:
- The final image of the object is formed on the **retina**. The retina acts as a screen that captures the light rays focused by the lens and converts them into neural signals that are sent to the brain.

4. **Conclusion**:
- Therefore, the correct answer to the question is that the human eye forms the image of an object on the **retina**.

### Final Answer:
The human eye forms the image of an object on the **retina**.
