Verified by Experts

The correct Answer is:
B
The combustion of fossil fuels increases the amount of suspended particles in air. These suspended particles could be unburnt carbon particles (i.e., hydrocarbons). Presence of high levels of these pollutant cause visibility to be lowered, especially in cold weather when water also condenses out of air. This is known as somg and it is a visible indication of air pollution.
