When an object is placed at the focal point of a concave mirror, no image is created because the light rays that reflect off the mirror diverge after reflecting. In this situation, the light rays converge at the focal point but do not form a real image at any location. Instead, all the reflected rays will travel parallel to the principal axis, leading to the formation of virtual images that cannot be seen on a screen. This is a key concept in optics regarding concave mirrors and emphasizes the relationship between object position and image formation.

The other choices do not accurately capture the behavior of light in this particular context. Understanding this phenomenon is critical in grasping how concave mirrors function in various applications, such as in telescopes or shaving mirrors.
