Correct option is D

An image which can be obtained on a screen is called a real image. So the answer is (d).
An image that can be obtained on a screen is called a real image. A real image is formed when actual light rays converge at a specific point after passing through an optical system, such as a lens. The light rays physically pass through the location of the image, allowing it to be projected onto a screen or a surface. This is different from a virtual image, where the light rays only appear to diverge from a specific point when traced backward and cannot be projected onto a screen.
