Virtual images can be obtained on a screen while real images cannot be obtained on a screenC. Virtual images are formed only in refraction and not in reflection while real images can be formed in bothD. Virtual images are formed only in reflection while real images are also only found in refraction.

Difference Between Real and Virtual Images
The basic difference between a real image and a virtual image lies in how they are formed and their properties, especially whether they can be projected onto a screen or not.
Here is a detailed explanation of each type of image:
1. Real Image:
• Formation: A real image is formed when light rays actually converge at a point after reflection or refraction. This means the light rays physically meet at a specific location and can be captured on a screen.
• Properties:
o Real images are inverted (upside-down) relative to the object.
o They can be projected onto a screen, as the light rays physically converge at the image location.
• Example: A real image is formed by a concave mirror when the object is placed outside the focal point, or by a convex lens when the object is placed at a distance greater than the focal length.
2. Virtual Image:
• Formation: A virtual image is formed when light rays appear to converge at a point, but they do not actually meet. Instead, the light rays only seem to diverge from a point behind the mirror or lens. These rays do not physically meet, making the image "virtual".
• Properties:
o Virtual images are usually upright (same orientation as the object).
o They cannot be projected onto a screen because the light rays don't actually converge at any point.
• Example: A virtual image is formed by a concave mirror when the object is placed inside the focal point, or by a convex lens when the object is placed inside the focal point.
Key Differences:
• Real Image: Can be obtained on a screen, is inverted, and formed by actual convergence of light rays.
• Virtual Image: Cannot be obtained on a screen, is upright, and formed by the apparent convergence of light rays
Answer to the Question:
A. Real images are the images that can be obtained on a screen, whereas a virtual image cannot be obtained on a screen.
This is the correct option because real images result from light rays converging at a point, so they can be projected onto a screen. In contrast, virtual images only appear to form where the rays seem to converge but do not physically meet, making them impossible to project onto a screen.
