Solution

The correct options are
B Irreversible.

Electrolysis of water into hydrogen gas and oxygen gas, therefore, it's a chemical change and since from water(liquid) to gas conversion, therefore, physical change as well and of course it is irreversible since hydrogen gas and oxygen when in contact don't produce water.
