B Correct answer
Explanation

Pearls are primarily calcium carbonate (CaCO3), which reacts with acids. Vinegar contains acetic acid (weak acid) that can dissolve calcium carbonate through the reaction: CaCO3 + 2CH3COOH → Ca(CH3COO)2 + H2O + CO2. While stronger acids like sulfuric and nitric would also work, vinegar is commonly cited in trivia about pearl dissolving.
