Vedclass · Answer

(B) Natural pollutants are substances released into the environment by natural processes rather than human activities. $1$. Pollen grains are natural allergens released by plants. $2$. Dusts from deserts (wind-blown dust) are natural particulate matter. $3$. Hydrocarbons released from vegetation (e.g.,terpenes) are natural volatile organic compounds. Carbon monoxide,smog,and sulphur dioxide are primarily associated with anthropogenic (human-made) activities like industrial emissions and vehicular exhaust. Therefore,option $B$ correctly lists natural pollutants.
