The correct answer is

Virtual image

An image that cannot be obtained on a screen is called a virtual image. In a virtual image, the reflected (or refracted) light rays only appear to diverge from a point — they do not actually converge there, so no real image can be captured on a screen.

A plane mirror always forms a virtual, erect, laterally inverted image of the same size as the object, located as far behind the mirror as the object is in front. A real image (formed e.g. by a concave mirror or convex lens) is the one that can be projected on a screen. Hence the answer is Virtual image.
