Hello student, here the question is given and the question is about this primary pollutant.
00:05
So we have to point out these primary pollutants in the given options.
00:11
So we know these primary pollutants are going to enter the air directly.
00:17
So this is going to enter the air directly from their particular sources and they mainly include the oxides or we can say the volatile organic compounds.
00:33
So these volatile organic compounds are produced naturally from the plant as well as human activities.
00:46
So they are going to produce by this plant as well as these human activities.
00:54
So for example, industrial solvent and the various hydrocarbons are going to be produced.
01:02
So this is the one which is the primary pollutant and if you look into the other options, so other option which are the primary pollutants are the particulate matter.
01:12
So this one is the e which is the particulate matter.
01:18
So this one is also a primary pollutant because this comes this dust, dirt, soot, ash as well as the smoke.
01:31
So all are the particulate matter and they are solid particle with the liquid droplet.
01:36
So these are the called as the particulate matter and this present inside the air directly and another one which is the involved in this primary pollutant is going to be the sulfur dioxide and this no oxide and the lead...
