The change that is a chemical change is:
water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules.
In this process, water is broken down into its constituent elements, oxygen and hydrogen, which changes the chemical composition of the substance, indicating a chemical change. The other options (freezing, evaporating, and boiling) involve physical changes that do not alter the chemical composition of water.
