What is the general nature of metal oxides?
Answer and explanation
Correct answer: Basic
The governing concept is the acid–base nature of oxides. Most metal oxides are basic because they react with acids to form salt and water; for example, CuO + 2HCl → CuCl₂ + H₂O. This neutralisation behaviour supports option B. Although some metal oxides may be amphoteric or neutral, the general school-level classification is basic, not acidic or sweet.
