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.
