Solution

The correct option is A On a rough surface, light is reflected in different directions.
Diffused reflection occurrs on rough surfaces such as clothing, paper, and the asphalt roadway. In diffused reflection, light is reflected in different directions even if the incident light beam is parallel and in a single direction.

On the other hand, regular reflection happens for smooth surfaces like a plane mirror. In regular reflection, parallel incident light beam remains parallel even after reflection.
