In a nickel-cadmium battery, which of the following reactions occurs at the anode during discharge?
A. \(Cd(s)+2OH^{-}(aq)\rightarrow Cd(OH)_{2}(s)+2e^{-}\)
B. \(Ni(OH)_{2}(s)+H_{2}O(l)+e^{-}\rightarrow NiOOH(s)+OH^{-}(aq)\)
C. \(Ni(OH)_{2}(s)+2e^{-}\rightarrow Ni(s)+2OH^{-}(aq)\)
D. \(Cd(OH)_{2}(s)+2e^{-}\rightarrow Cd(s)+2OH^{-}(aq)\)
