Solution

The correct option is D

an irregular reflection is taking place from a rough surface


The given figure shows that the parallel incident rays become unparallel after reflection from the given surface. Therefore, the reflection from the given surface is not regular. A reflection is said to be irregular if the reflected rays are not parallel for parallel incident rays. Such reflections take place from rough surfaces only. Hence, an irregular reflection is taking place from a rough surface in the given figure.
