Electrolysis uses electrical current to break water molecules into oxygen gas and hydrogen gas. How do you know that this is a chemical change?

Chemical bonds in the water molecule are broken.
There is a phase change from liquid to gas.
Electrical current always causes a chemical change.
It is a single replacement reaction.

I think it could be A or D
