(C) During the electrolysis of dilute $H_2SO_4$,the following reactions occur:At the cathode: $2H^+_{(aq)} + 2e^- \rightarrow H_{2(g)}$At the anode: $2H_2O_{(l)} \rightarrow O_{2(g)} + 4H^+_{(aq)} + 4e^-$Since the oxidation potential of water is higher than that of the sulphate ion $(SO_4^{2-})$,water is oxidized at the anode to release oxygen gas.
