Solution

## The correct option is D XAccording to the first law of reflection, the angle of incidence is equal to the angle of reflection. The incoming rays from W and Y strikes the mirror and gets reflected in another direction. They can't see their image in the mirror as the reflected ray won’t reach their eyes. Z will not be able to see his image as the incident ray from Z is parallel to the plane of the mirror. Only X can see his image in the mirror as the rays coming from X get reflected by the mirror and reaches his eyes. Hence, the correct option is B i.e. boy X.
