Correct option (a) Both A and R are true and R is the correct explanation of A
Explanation:
Oxygen is the most electronegative element after fluorine. Therefore, in the compounds between oxygen and fluorine, oxygen is found to show positive oxidation state.
e.g., OF2: Oxygen difluoride.
Oxidation state of oxygen here is +2.
