Low visibility during cold weather is due to:


Formation of fossil fuel


Unburnt carbon particles or hydrocarbons suspended in air


Lack of adequate power supply


None of these


During cold weather, water droplets instead of moving up at a higher altitude stays near the earth's surface and cause fog. Along with this, a lot of vehicular emissions and smoke from industries include unburnt carbon and hydrocarbons, these particles get mixed with the already suspended fog and lead to the formation of smog. This smog suspends closer to the surface of earth causing visibility issues along with nasal congestions and other nasal infections.
