Why are marble monuments like the Taj Mahal affected by acid rain?
Answer and explanation
Correct answer: Acid can react with marble
The governing concept is the reaction of acids with carbonates. Marble is mainly calcium carbonate, CaCO₃. Acids present in acid rain react with it, gradually dissolving or altering the stone and sometimes producing salts, water, and carbon dioxide. Therefore option A is correct. Acid rain cannot turn marble into gold; it is not neutral, and marble is a solid rock rather than a gas.
