Which of the following statement(s) is/are correct? A. Oxides of non-metals are basic B. Oxides of non-metals are acidic C. Oxides of metals are acidic D. All option are correct

The correct answer is: B. Oxides of non-metals are acidic.

Oxides of non-metals are acidic because they react with water to form acids. For example, carbon dioxide reacts with water to form carbonic acid:

$CO_2 + H_2O \to H_2CO_3$

Oxides of metals are basic because they react with water to form bases. For example, sodium oxide reacts with water to form sodium hydroxide:

$Na_2O + H_2O \to 2NaOH$

Option A is incorrect because oxides of non-metals are not basic. Option C is incorrect because oxides of metals are not acidic. Option D is incorrect because not all of the statements are correct.
