Vedclass · Answer

(C) The correct answer is $C$. According to the Central Pollution Control Board $(CPCB)$,particulate matter of size $2.5 \ \mu m$ or less in diameter (referred to as $PM \ 2.5$) is considered the most harmful to human health. These fine particles can penetrate deep into the respiratory system,reaching the lungs. Exposure to these particles causes breathing and respiratory problems,irritation,inflammation,and damage to the lungs,which can lead to premature death. While they do not enter the circulatory system directly,they cause significant systemic damage through the respiratory tract.
