Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The potential is always determined with respect to standard hydrogen electrode taking it as reference as 0 because it is the potential difference that is important. Absolute potential cannot be determined.
Hence, option B is correct.
