Solution

The correct option is B
$C_{1} > C_{2}$

Given cell is electrolyte concentration cell
$E_{c e l l} = \frac{R T}{F} l n \frac{[A g^{+}]_{c a t h o d e}}{[A g^{+}]_{a n o d e}}$

Where $[A g^{+}] = \frac{K_{s p}}{[C l^{-}]}$
For spontaneous chemical change conc. of $A g^{+}$ of cathodic compartment must be greater than anodic compartment.
