C) both absolute and standard electrode potential values are zero D) electrode potential is zero only at 25 deg C
 
Answer & Explanation Answer: A) absolute electrode potential is not zero

Explanation:

The Standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts only at 298.
