Solution

The correct option is A $A g$ from $A g$ anode dissolves while $A g^{+}$ from solution gets deposited on the cathode.
The chemical equation for the electrolysis of $A g N O_{3}$ is:

$A g N O_{3} \to A g^{+} + N O_{3}^{-}$ (aqueous solution )
Reaction at cathode :

$A g_{a q}^{+} + e^{-} \to A g^{+}$ ; $E^{0} = + 0.80 V$

$2 H_{2} O_{(} l) + 2 e^{-} \to 2 O H^{-}$ ; $E^{0} = - 0.83 V$

Since reduction potential of Ag is higher than $H_{2} O$ , the $A g^{+}$ ions are reduced to Ag.

Reaction at anode :
$A g \to A g_{(a q)}^{+} + e^{-}; E^{o} = - 0.80 V$

$2 H_{2} O \to O_{2} + 4 H^{+} + 4 e^{-}; E^{0} = - 1.23 V$

Since the oxidation potential of Ag is higher than $H_{2} O$ , Ag of silver anode is oxidized. The potential of $N O_{(3}^{-}$ is lower than $H_{2} O .$

Therefore, option A is the correct answer.
