Correct answer: C — Previous asbestos exposure

Pleural plaques, diaphragmatic calcification and basal fibrosis are classic for asbestos-related pleural disease with asbestosis. Coal and silica more often produce upper-zone nodular disease and progressive massive fibrosis. Nitrofurantoin can cause ILD but would not explain calcified pleural plaques.
