Correct Answer - D
(d) Electrolysis of both KCl and NaCl solutions liberates `H_(2)` at the cathode and `Cl_(2)` at the anode. Thus, the distinction cannot be made by the gases evolved at the two electrodes. However, resulting solutions will be different. KOH in case of KCl and NaOH in case of NaCl.
