Solution

The correct option is C aqueous AgNO $_{3}$ solution between Ag electrodes
When the metal electrodes and the salt are of the same metal and metal has higher reduction potential then $H^{+}$ , then the electrodes act as active electrodes
These conditions are true for aq. $A g N o_{3}$ solution between Ag electrodes.
