When non-metals combine with oxygen, they typically produce acidic oxides. This is because non-metals can form covalent bonds with oxygen, leading to the creation of substances that, when dissolved in water, tend to form acids. For example, sulfur combines with oxygen to form sulfur dioxide (SO₂), which can further react with water to form sulfurous acid (H₂SO₃). Similarly, phosphorus can combine with oxygen to form phosphorus pentoxide (P₂O₅), which forms phosphoric acid (H₃PO₄) in water.

Thus, the correct answer is:

### Final Answer
**A. Acidic oxides**
