Solution
The correct option is B basic Ionic metal oxides react with water to give hydroxides (compounds
containing the hydroxyl ion) and resultant solution is basic, whereas most
non-metal oxides react with water to form acids and resultant solution is acidic. For example, sodium oxide reacts with water to form sodium hydroxide which is a strong base. Na2O+H2O→2NaOH
