The change that is chemical is:
**Water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules.**
This process involves breaking the chemical bonds in water (H2O) to form different substances (oxygen and hydrogen), which is a chemical change. The other options are physical changes, where the substance remains the same overall, just in a different state (solid, liquid, or gas).
