Answer: [C] Brown carbon

Correct answer is Brown Carbon, which contributes 30 % in damage to Taj Mahal. As per recent analysis of Centre for Science and Environment (CSE), Sulphur dioxide is not the major contributor to damage now, as it was during 1990s. Vehicle emissions are the biggest contributors for brown and black carbon.
