Correct Answer: Option C
Explanation:
The correct answer is C: an oxide whose solution in water has a pH less than 7.
Anhydrides are typically non-metal oxides that, when dissolved in water, form acidic solutions, thus having a pH lower than 7. For example, sulfur dioxide (SO₂) forms sulfurous acid (H₂SO₃) when it dissolves in water.
