List I (Cause)	List II (Occupational Disease)
A. Coal dust	(I) Lung cancer
B. Asbestos	(II) Silicosis
C. Iron	(III) Anthracosis
D. Aromatic amines	(IV) Bladder cancer

(a) a-II, b-III, c-I, d-IV (b) a-I, b-II, c-III, d-IV (c) a-III, b-IV, c-II, d-I (d) a-II, b-III, c-I, d-IV

Correct option is C

Occupational diseases are caused by long-term exposure to harmful substances in specific work environments.
· (a) Coal dust → (III) Anthracosis Anthracosis (black lung disease) occurs due to prolonged coal dust inhalation, common in coal miners.
· (b) Asbestos → (IV) Bladder cancer Asbestos exposure is linked to lung diseases and bladder cancer.
· (c) Iron → (II) Silicosis Silicosis is caused by inhalation of silica particles, affecting iron and stone industry workers.
· (d) Aromatic amines → (I) Lung cancer Aromatic amines, found in dyes, chemicals, and tobacco smoke, are known carcinogens causing lung cancer.
