Which of the following is a physical change

A physical change is a change in which the substance changes its physical shape, but chemically, its still the same.

For example, ripping a paper in half.

Its still paper, so its a physical change. But if I were to set it on fire, it would be a chemical change.

Physical changes can always go back to their original states.

Examples:

paper being torn can be taped back together and still be paper

however, paper being burned is now ash and smoke (Chemical change)
