• C. lack of adequate power supply
• D. none of these

Answer 1

The correct option is B

unburnt carbon particles or hydrocarbons suspended in air

The correct option is (B):-

Explanation for the correct answer:-

Formation of Smog:-

1. During winters, there would be the formation of fog as the water droplets will condense in the air and the level of visibility will get lower by time.
2. The dust particles will also stick around the droplets which will further lower the visibility.
3. This all phenomenon will result in the formation of the Smog ( smoke + fog ) ,lowering the visibility in the cold weather seasons which is also harmful for the animals, plants and human beings.

Therefore, the correct option is (B):- unburnt carbon particles or hydrocarbons suspended in air.
