(d) It will not be liberated at anode
Explanation:
Hydrogen has same IP as alkali metals. Hydrogen has same electronegativity as halogens. Hydrogen has +1 oxidation state in compounds with more electronegative elements e.g. HF. It has -1 oxidation state in compounds with more electropositive elements like NaH. In the above compounds with Na and F show +1 and -1 oxidation state respectively.
Statement D is incorrect. Hydrogen is not liberated at anode.
Option D is the answer.
