Answer:
C. Pneumoconiosis
Step-by-step explanation:
The condition that reflects immunologically mediated lung disorder due to prolonged, intense exposure to organic dusts is Pneumoconiosis. Pneumoconiosis is caused by inhalation of mineral dusts, such as silica and carbon, and is characterized by interstitial fibrosis and impaired gas exchange. The risk of developing pulmonary fibrosis increases with the number of work years of exposure. Dust containing steel, brass, lead, and pine wood are most likely to cause pneumoconiosis.
