Solution

The correct option is A True

Real images: A real image is an image formed by actual rays of light. Real images are always inverted, and they may be either larger or smaller than the object.

Virtual images: An image, that seen in a mirror, in which the rays of light appear to be emanating from some object that is not there is called a virtual image. Virtual images are always erect. They, also, may be either larger or smaller than the object.

A slide projector produces a real, inverted and magnified image. The image must be real, because otherwise you would not be able to project it onto a screen. The image is inverted, so the slides have to be put in upside down. A projector uses a convex lens. A magnifying glass also uses a convex lens. The image is upright, magnified and virtual. The object must be at or within the focal length of the lens.
