Final Answer :
D
Explanation :
In a physical change, the state of matter of a substance is altered (e.g., solid to liquid, liquid to gas), but its chemical identity remains the same. This can include changes in shape, size, or phase of matter, but does not involve changing the substance into a different substance.
