Correct answer: A. Base
- A. Base
- B. Acid
- C. Salt
- D. Basic anhydride
Explanation
Metallic oxides that are basic will react with water to form a basic solution. For example, sodium oxide (Na2O) reacts with water to form sodium hydroxide (NaOH), a strong base. Therefore, the most likely product formed when a metallic oxide is added to water is a base.

About Bronsted-Lowry and Lewis Concepts
The Brønsted-Lowry concept defines acids as proton donors and bases as proton acceptors, producing conjugate acid-base pairs. The Lewis concept extends the idea to electron-pair acceptors and donors, so compounds such as BF3 and NH3 can be treated as acid and base even without proton transfer, unlike the Arrhenius definition.
