(C) The cell reaction is: $Cu_{(s)} + 2Ag^{+}_{(aq)} ightarrow Cu^{2+}_{(aq)} + 2Ag_{(s)}$.The Nernst equation is: $E_{	ext{cell}} = E^{\circ}_{	ext{cell}} - \frac{0.059}{2} \log \frac{[Cu^{2+}]}{[Ag^{+}]^2}$.For the first cell: $0.3095 = E^{\circ}_{	ext{cell}} - \frac{0.059}{2} \log \frac{0.1}{(0.01)^2} = E^{\circ}_{	ext{cell}} - \frac{0.059}{2} \log(1000) = E^{\circ}_{	ext{cell}} - \frac{0.059}{2} 	imes 3$.$E^{\circ}_{	ext{cell}} = 0.3095 + 0.0885 = 0.398 \ V$.For the second cell: $E_{2} = 0.398 - \frac{0.059}{2} \log \frac{0.01}{(0.001)^2} = 0.398 - \frac{0.059}{2} \log(10000) = 0.398 - \frac{0.059}{2} 	imes 4 = 0.398 - 0.118 = 0.28 \ V$.$0.28 \ V = 28 	imes 10^{-2} \ V$.
