Some standard electrode potentials at 298 K are given below: Pb+/Pb -0.13

Some standard electrode potentials at 298 K are given below: Pb+/Pb -0.13 V Ni2+ Ni 0.24 V Cd+/Cd-0.40 V Fe2+/Fe 0.44 V To a solution containing 0.001 M of X+ and 0.1 M of Y+, the metal rods X and Y are inserted (at 298 K) and connected by a conducting wire. This resulted in dissolution of X. The correct combination(s) of X and Y, respectively, is(are) (Given: Gas constant, R = 8.314 J K mol, Faraday constant, F = 96500 C mol-) (A) Cd and Ni (C) Ni and Pb (B) Cd and Fe (D) Ni and Fe
