Some standard electrode potentials at 298K are given below:

To a solution containing 0.001M of `X^(2+)` and 0.1M of `Y^(2+)`, the metal rods X and Y are inserted (at298K) and connected by a conducting wire. This resulted in dissolution of X. The correct combinations of X and Y, respectively is (are)
(Given: Gas constant, `R=8.314JK^(-1)mol^(-1)`, Faraday constant,F= 96500C`mol^(-1)`)
