Best answer
Right answer is (d) Oxides which are acidic

The best explanation: Non-metals form acidic oxides because upon dissolution in water they liberate free H^+ ions. Oxides with pH <=7 also include neutral oxides and not acidic only. Oxides with pH > 7 are basic in nature. Amphoteric oxides behave both like acid and base.
