Solution

The correct option is C Plane mirror
In order to obtain a patch of light at B, light from the torch must bounce from A to B. A plane mirror reflects light and thus, changes the path of light falling on it. Hence, if a plane mirror is kept at A, light from the torch will get reflected by it and reach B.
