Solution

The correct option is D Paper is neutral and comb is charged
When a comb is rubbed over the hair on our head, it gets charged. When it is brought near small pieces of paper, it attracts the paper. This happens even though the pieces of paper are neutral due to rearrangement of charge inside paper.
