(B) $PM\ 2.5$ refers to particulate matter with a diameter of $2.5 \ \mu m$ or less. These particles are considered the most harmful to human health according to the Central Pollution Control Board $(CPCB)$.They are small enough to be inhaled deep into the lungs,where they cause respiratory problems,irritation,inflammation,and damage to lung tissues,potentially leading to premature death.While they significantly impact the respiratory system,they do not directly enter the circulatory system; their effects on the circulatory system are indirect,occurring through the respiratory pathway.Therefore,the statement that they can directly enter the circulatory system is incorrect.

Which one of the following is not correct with regard to the harmful effects of particulate matter of the size $2.5 \ \mu m$ or less?
