Vedclass · Answer

(C) $1$. According to the $CPCB$ (Central Pollution Control Board),particulate matter of size $2.5 \ \mu m$ or less in diameter $(PM_{2.5})$ is responsible for causing the greatest harm to human health.$2$. These fine particulates can be inhaled deep into the lungs and cause respiratory problems,inflammation,and damage to the lungs,not the heart directly.$3$. Catalytic converters,fitted into automobiles for reducing emission of poisonous gases,have expensive metals namely platinum-palladium and rhodium as the catalysts.$4$. Since statement $A$ and $C$ are factually correct based on $NCERT$,and statement $B$ is a common misconception (it affects lungs),the question implies selecting the most accurate scientific statements. Given the options,$C$ is the most accurate description of catalytic converters.
