An aqueous solution containing one mole per litre of each Cu(NO3)2, AgNO3. Hg(NO3)2, Mg(NO3)2 is being electrolysed using inert electrodes. The values of standard electrode potential in volts (reduction potential) areAg / Ag+ = + 0.80V  Hg2+ / Hg = + 0.79VCu2+ / Cu = + 0.34V  Mg2+ / Mg = – 2.37VWith increasing voltage, the sequence of deposition of metals on cathode will be
