Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The potential of standard hydrogen electrode is $0.00 V$ . Hence, the standard electrode is a half cell having $1 M$ $H^{+}$ concentration bubbled with hydrogen at any pressure. So, both assertion and reason are correct.
