Potential is a relative term i.e it is always measured with respect to a reference in electrochemistry, hydrogen is taken to be the reference to measure the potential and hence to form a basis for comparison with all other electrode reactions...
Hydrogen's standard electrode potential is declared to be zero volts at all temperatures...

Hence, the correct answer is option (B)...
