B. Changes can occur to certain physical properties of the substance, but the overall shape of the substance will remain the same.

D. Changes can occur to chemical properties of a substance, but the chemical composition of the substance remains the same.

Answer 1

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!
