Solution

The correct option is D Polished marble floor
Regular reflection occurs at highly smooth surfaces. Any surface that is polished will have a smooth surface. Among the given options, the polished marble surface has maximum smoothness. Thus, regular reflection takes place on polished marble floor.

However, cement road, sand paper, and a rough wooden table forms a rough surface. Any reflection happening there is diffused reflection.
