The pathogenesis of pneumonia is:
A. interstitial and alveolar wall thickening, inflammation, and lung destruction.
B. inhalation of dust, formation of antigen-antibody complexes, inflammation, and granulomas production.
C. inhalation of microbial agents, inflammation, formation of exudates, and fibrosis resulting in lung consolidation.
D. injury/damage to the alveolar-capillary membrane and disruption in oxygen transport and utilization resulting in decreased lung compliance.
