Assertion (A): The products of electrolysis of water are hydrogen and oxygen.
Reason ( R): In electrolysis process of water, hydrogen ions are attracted to anode and hydroxyl ions are attracted to cathode.

A

Both (A) and ( R) are true and ( R) is the correct reason for (A).

B

Both (A) and ( R) are true but ( R) is not the correct reason for (A).
