Solution

The correct option is B

H2 (gas) and O2 (gas)


Reduction potential of water > Reduction potential of Li. So, at cathode water gets reduced to give hydrogen gas.

Similarly, oxidation potential of water < oxidation potential of sulphate ions.

So, at anode water gets oxidized to give oxygen.
