Final Answer :
A
Explanation :
Fine and ultrafine suspended particles can penetrate the lungs' natural defences and enter into the deeper parts of the lung, causing various respiratory and cardiovascular health problems. Ozone, large suspended particles, and acid rain do not penetrate the lungs to the same extent as fine and ultrafine particles.
