Mark the correct one.

Options

A. Our eyes can distinguish between real and virtual image
B. Virtual image can also be taken on screen
C. If the incident rays are converging at a point, then the object is real
D. None of the above

Explanation

To solve the question, we need to analyze each statement provided and determine whether it is true or false based on our understanding of optics, specifically regarding real and virtual images.

### Step-by-Step Solution:

1. **Understanding Real and Virtual Images**:
- A **real image** is formed when light rays converge and can be projected onto a screen. It is inverted and can be captured on a surface.
- A **virtual image** is formed when light rays appear to diverge from a point. It cannot be projected onto a screen and is upright.

2. **Analyzing the First Statement**:
- The first statement claims that our eyes can distinguish between real and virtual images. This is incorrect because all images formed on the retina are real images. The retina acts as a screen for image formation, meaning we cannot distinguish between real and virtual images based on what we see.

3. **Analyzing the Second Statement**:
- The second statement suggests that a virtual image can be taken on a screen. This is also incorrect because virtual images cannot be projected onto a screen; they are formed by the apparent divergence of light rays.

4. **Analyzing the Third Statement**:
- The third statement posits that if incident rays are converging at a point, then the object is real. This statement is misleading. An object is considered real when the rays diverge from it, not when they converge at a point. Therefore, this statement is also incorrect.

5. **Conclusion**:
- All three statements provided in the question are incorrect. Hence, none of them can be marked as correct.

### Final Answer:
All the statements are incorrect.
