The lens refracts light outward, generating a virtual image.
The lens refracts light outward, forming a real image.
The lens refracts light inward, generating a virtual image.
The lens refracts light inward, producing a real image.

Answer 1

The correct answer is: The lens refracts light inward, producing a real image.

Convex lenses bend (refract) light rays that pass through them inward (converging them) to a focal point, and if the object is positioned outside the focal length, this leads to the formation of a real image that can be projected onto a screen.
