Answer 1

The correct option is A smoke and fog

Smog is a type of air pollution. The word 'Smog' is made up of smoke and fog.

Smoke is a cloud of very small solid particles produced when something is burned in the flame. Fog is a visible aerosol consisting of minute water droplets or ice crystals suspended in the air. So when the smoke gets mixed with fog it produces the smoke.

so the correct answer is 'smoke and fog'.
