Solution

The correct options are
B $M g (N O_{3})_{2}$ can be stored in copper vessel.
C $C u C l_{2}$ can be stored in silver vessel.
The idea is that the electrolyte should stay in its ionic form and the vessel must not dissolve.
So, the vessel needs to be the cathode and the electrolyte the anode for this to happen.
All the cells that have a +ve $E^{\circ}$ va;use when this setup is made would be feasible.
Remember, $E^{\circ} = E_{c a t h o d e}^{\circ} - E_{a n o d e}^{\circ}$
