Microbiology Why Sputum Filled with Pus?

A 57-year-old man presents with an episode of shaking chills the previous night. He has now developed right-sided pleuritic chest pain, fever, sweats, malaise, purulent sputum, and mild hemoptysis. On examination,the patient is diaphoretic but alert, with right basilar rales. Chest X-ray films show a right lower lobe infiltrate with blunting of the right costophrenic angle. Why is this patient's sputum filled with pus?

A. Teichoic acids and peptidoglycan are chemotactic for neutrophils
B. The capsule of the causative agent is chemotactic for neutrophils
C. The causative agent is an intracellular organism
D. The causative agent is beta hemolytic
E. The organism produces an IgA protease
