When we see an object, image formed on the retina is
(i) real (ii) virtual
(iii) erect (iv) inverted

Options

A. real and inverted
B. virtual and erect
C. real and erect
D. virtual and inverted

Explanation

To solve the question regarding the nature of the image formed on the retina when we see an object, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Eye's Structure**:
- The human eye contains a lens that is shaped like a convex lens. This lens is responsible for focusing light onto the retina.

2. **Light Rays and Image Formation**:
- When light rays from an object enter the eye, they converge through the convex lens. Depending on the distance of the object, parallel rays of light will converge at a point on the retina.

3. **Characteristics of the Image**:
- The image formed by a convex lens is real. This is because the light rays actually converge at the retina, rather than appearing to diverge from a point behind the lens (which would create a virtual image).
- The image is also inverted. This is a characteristic of images formed by convex lenses; they flip the image upside down.

4. **Conclusion**:
- Therefore, when we see an object, the image formed on the retina is **real and inverted**.

### Final Answer:
The image formed on the retina is (i) real and (iv) inverted.
