An aqueous solution containing one mole per litre of each `Cu(NO_3)_2 , AgNO_3 . Hg(NO_3)_(2), Mg(NO_3)_2` is being electrolysed using inert electrodes. The values of standard electrode potential (reduction potential) in volts are
`Ag//Ag^(+) = + 0.80 V " "Hg//Hg^(2+) = + 0.79V " " Cu//Cu^(2+) = +0.34 V " " Mg//Mg^(2+) = -2.37 V `
With increasing voltage, the sequence of deposition of metals on cathode will be

A

Ag, Hg, Cu, M,g
