The answer to your question is letter C

Explanation:

A physical change is when matter changes its physical change, but the substance stays the same Ex, evaporation, condensation, etc

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

This option is wrong because in a physical change there are no changes in the chemical properties.

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

This is the wrong because in a physical change there are changes in the physical properties and also the shape of the substance changes.

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

This is the right option because in a physical change, there are changes in the physical properties and the chemical composition remains the same.

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

This option is wrong because if there is a physical change, them it isn't a physical change.
