Solution

The correct option is B Both assertion and reason are true but the reason is not the correct explanation of assertion

In the industrial area, where there are a lot of industries such as chemical factories, motor vehicles and thermal power stations present air pollution is very high. As a result, gases such as sulphur dioxide and nitrogen dioxide are present in large extent. These gases dissolve in rainwater and reach the earth surface as acid rain. As a result, the marble used in the construction of Taj Mahal is fading away. The acid rain corrodes the marble and results in the fading.
