Your answer would be C as a physical change is characterized as a change in physical appearance be it shape, phase, or size. A good example is an ice cube when it melts, it may look different but its chemical composition is the same and the change from is ice to water is reversible unlike a chemical change like baking a cake which cannot be reversed to its original state before it went into the oven. Hope this helps!
