Correct answer: (A) Ultra-fine sized particulate matter

Explanation

Atmospheric haze is mainly caused by ultra-fine particulate matter suspended in the air.

These tiny particles scatter light, reducing visibility and dimming the sky.

Oxides of nitrogen and sulphur are gases that form particles only after reactions.

Ozone is a reactive gas linked to smog rather than the haze effect directly.

Carbon dioxide and carbon monoxide are colourless gases and do not cause haze.

Fine aerosols also affect climate by scattering incoming sunlight.
