• D. 1.5 or less

Answer 1

The correct option is A 10 or less

According to Central Pollution Control Board (CPCB), which particulate size in diameter (in micrometers) of the air pollutants is responsible for greatest harm to human health is 10 or less.
Particle pollution also called particulate matter or PM is a mixture of solids and liquid droplets floating in the air. Particles come in a wide range of sizes.Particles less than or equal to 10 micrometers in diameter are so small that they can get into the lungs, potentially causing serious health problems.
