Answer:
The phenomenon of marble cancer is due to (d) acid rain.
Explanation:
The marble cancer is the corrosion of the buildings and statues made up of marble due to the action of sulphuric acid and nitric acid.
[tex]SO_{2}[/tex] and [tex]NO_{x}[/tex] are produced due to pollution.
When these oxides mix with the rain drops in the cloud, they form sulphuric acid and nitric acid. When these acids come in contact with the marble, they cause corrosion.
Hence, acid rain causes the phenomenon of marble cancer.
