• B. Acid rain
• C. 3, 4 benzpyrene

Answer 1

Answer: (B)

Acid rain

The reduction in the shine of Taj mahal is understood by the term called as marble cancer. Various pollutants are emitted by the industries situated near Agra, specially the Mathura refinery. These pollutants react with the marble forming a fine layer of dust over it and also various gases like sulphur dioxide and nitrous oxide combines with moisture and settles down as acid rain on the walls of the monument thus provides a yellow tingle to its pure white marble.

So, the correct answer is option B.
