The change that is chemical is:
Water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules.
This is a chemical change because the process of electrolysis breaks the chemical bonds in water (H₂O) to form different substances (hydrogen gas and oxygen gas). The other processes listed (freezing, boiling, and evaporating) are physical changes, where the substance changes its state but not its chemical composition.
