An electrochemical cell was constructed with $$\text{Fe}^{2+}$$/Fe and $$\text{Cd}^{2+}$$/Cd at $$25^\circ\text{C}$$ with initial concentrations of $$[\text{Fe}^{2+}]$$ = 0.800 M and $$[\text{Cd}^{2+}]$$ = 0.250 M. The EMF of the cell when $$[\text{Cd}^{2+}]$$ becomes 0.100 M is

A

0.013 V

B

0.011 V

C

0.051 V

D

0.022 V
