What type of images are formed by a concave mirror?

A concave mirror can form real images that can be projected onto a screen, which is why the selected answer is accurate. When light rays converge after reflecting off the inward-curved surface of a concave mirror, they meet at a single point, creating a real image. This is particularly evident when the object being reflected is placed outside the focal length of the mirror.

As the object moves closer to the mirror, different types of images can be produced: for objects located beyond the center of curvature, the real images formed tend to be inverted and reduced in size; when the object is at the focal point, the rays reflect in such a way that they diverge, leading to a situation where no clear image is formed.

In contrast, options that suggest the mirror only creates virtual images, distorted images, or only upright images do not reflect the full capabilities of a concave mirror. While it's true that when an object is placed between the focal point and the surface of the mirror, the image formed is virtual and upright, this does not encompass all possible scenarios, particularly where real images are concerned when the object is positioned further away. Thus, concave mirrors are versatile in that they can produce both real images, which can indeed be projected,
