(A) The standard hydrogen electrode $(SHE)$ is used as a reference electrode.By convention,the standard electrode potential of $SHE$ is assigned a value of $0.00 \ V$ at all temperatures.Since the oxidation and reduction processes are reverse of each other,the potential values are equal in magnitude but opposite in sign.However,for $SHE$,both the standard oxidation potential and standard reduction potential are defined as $0.00 \ V$.
