The correct answer is that Non-metallic oxides are basic in nature.
• To test the acidity and basicity of these metal oxides, they are made with water and then react with water, and then tested with litmus paper.
• A basic solution turns litmus to blue whereas an acidic solution turns blue litmus to red.
