Which of the following is a pneumoconiosis condition?

Pneumoconiosis refers to fibrotic lung disease caused by inhalation of inorganic dust. Coal worker's lung fits this category because it results from inhaling coal dust, leading to deposition of dust in the lungs and progressive fibrosis, often starting in the upper lobes with nodular changes that can progress to progressive massive fibrosis. The other options are forms of hypersensitivity pneumonitis, which are immune-mediated responses to organic antigens (bird proteins in bird fancier’s or “bird breeders” lung, moldy hay in farmer’s lung, and organisms in hot tubs causing hot tub lung). These conditions cause inflammatory changes and granulomatous or interstitial inflammation rather than the classic dust-induced fibrotic lung disease seen in pneumoconiosis.
