Heya ItzRockingStar,

As per question,

• Catalytic converters can separate particulates of diameter less than 2.5

Explanation:

I understood your doubt but there is an uncertainty for it. There is no perfect count for how much diameter of particulate matter a catalytic converter can separate. Even due to the pollutants less than 2.5 diameter are causing diseases to humans and animals.

However, as per current sources of information from teachers, we can believe that catalytic converters can separate particulates of diameter less than 2.5 .

Most probably, it's exact answer might be found in the future era.

So currently, you can say that catalytic converters can seperate particulates of less than 2.5 diameter.

Hope it helps you!

:)

Answer:

Correct option 1)Catalytic converter can separate particulate matter of diameter less than 2.5 micrometers.

:According to Central Pollution Control Board CPCB. particulate size 2.5 micrometers or less in diameter PM 2.5 are responsible for causing the greatest harm to human health.

These fine particulates can be inhaled deep into the lungs and can cause breathing and respiratory symptoms such as irritation inflammations and damage to the lungs and premature deaths.
