Some standard electrode potentials at 298 K are given below:
Pb 2+ /Pb -0.13V
Ni 2+/ Ni -0.24V
Cd 2+ /Cd-0.40V
Fe 2+ /Fe -0.44V
To a solution containing 0.001 M of X 2+ and 0.1 M of Y 2+ , 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 -1 mol -1 , Faraday constant, F = 96500 C mol -1 )

(a,b,c)
Cd + Ni +2 
Cd +2 + Ni
= 0.11 + 0.06 = 0.33(+ve)
= -0.20 + 0.06 = -0.14(-ve)
