How can acid rain damage marble buildings?

Answer and explanation

Correct answer: Acid can react with calcium carbonate in marble

Marble contains calcium carbonate, CaCO3, a carbonate salt. Acids react with carbonates to form a salt, water, and carbon dioxide; in general, acid + carbonate produces salt + H2O + CO2. Repeated acid-rain contact can therefore dissolve or roughen the marble surface and damage structures. Option A correctly states the governing reaction, while the other claims contradict it.
