Correct answer
Aacid rain
Step-by-step explanation
Taj mahal is slowely disfigured and discoloured due to acid rain.
The primary acid component of acid rain is sulfuric acid(H2SO4) which reacts with Marble(CaCO3) and gives aqueous ion. This aqueous ions get washed away in the water flow and marble get disfigured and discoloured.
CaCO3(s) + H2SO4
Ca2+(aq) + SO42-(aq) + H2O + CO2
