The correct option is A NO and N2O
Acidic oxides are the oxides that form acids on reacting with water and are generally oxides of non-metals. Besides oxides of non-metals, the oxides of some metals in higher oxidation numbers are also acidic in nature.
Basic oxides are the oxides that form bases on reacting with water and generally oxides of metals. Generally, group one and group two elements except beryllium and all transition metals form basic oxides.
Neutral oxides show neither basic or acidic properties and hence these do not form salts on reacting with acids or bases.
NO and N2O are neutral oxides and N2O3,NO2 and N2O5 are acidic oxides.
