The pathogenesis of tuberculosis is:
A. inflammation, damage to the alveolar-capillary membrane, and formation of exudates.
B. entrance of mycobacteria into the lungs, activation of macrophages, formation of granulomas, fibrosis, and calcification.
C. interstitial and alveolar wall thickening, inflammtion, and noncompliant lungs
D. formation of antigen-antibody complexes, granuloma production, and fibrosis of the lung.
