The correct answer is D. HNO3.
Lead is a metal that is not very reactive. It does not react with water or air, and it does not dissolve in most acids. However, lead does dissolve in nitric acid (HNO3). This is because nitric acid is a strong acid that can break down the lead metal. The lead ions (Pb2+) that are formed in this reaction are then soluble in the nitric acid solution.
The other options are incorrect because they are not strong enough acids to dissolve lead. Acetic acid (CH3COOH), hydrochloric acid (HCl), and sulfuric acid (H2SO4) are all weak acids. They can dissolve some metals, but they cannot dissolve lead.
In conclusion, the only acid that can dissolve lead is nitric acid (HNO3).
