Solution
The correct option is C The original paper can be obtained from the cut piece.
Making stars by cutting it out from a paper isn't a reversible change because once you cut out a star you can't join it back to make same paper. Maybe you could tape it together, but it won't give you back the paper you started with exactly as it was. It would be a mess of cut paper and tape. Yuck!
This is a physical and irreversible change.
