Solution
The correct option is C Chalk powder
Regular reflection occur at highly smooth surfaces. Any surface that is polished will have a highly smooth surface. Among the options, polished marble floor and polished wooden table have very smooth surfaces. Thus, regular reflection takes place on those surfaces. Also, plane mirror is very smooth. It's probably the smoothest of surfaces. Regular reflection occurs there also.
However, chalk powder forms a rough surface. Any reflection happening there is diffused reflection.
