Solution

The correct option is E Both assertion and reason are incorrect
Virtual image is image where light rays only appear to cross but actually they do not pass through. Yes virtual images can be seen because the lens of our eye converge the rays into a real image and projected on our retina. Hence, we can see virtual image.
Virtual images are formed by diverging lenses or by placing an object inside the focal length of a converging lens. The ray-tracing exercise is repeated for the case of a virtual image. In this case the virtual image is upright and shrunken.
