Show Answer
Answer : b
Hints & Solution
(b) Silicosis is an occupational disease caused due to excess inhalation of silica dust in the workers involved grinding or stone breaking industries. Diagnosis is made when someone who has worked with silica has chest computed tomography (CT) that shows distinctive patterns consistent with the disease. A chest $x$-ray can also be done to help diagnose silicosis. When imaging findings are unclear, samples of lung tissue can help confirm the diagnosis.
