Correct answer: C — Grain dust lung disease (occupational COPD and bronchiectasis from grain dust exposure)

Grain dust is a recognised cause of occupational respiratory disease including COPD, bronchiectasis, and grain fever. The pattern of emphysema and bronchiectasis in a dock worker with grain exposure is consistent with grain dust lung disease.
