PART B: Which detail from the text best supports the answer to Part A?

B.“When T cells specifically recognize influenza virus proteins, they then begin to proliferate in the lymph nodes around the lungs and throat. This causes swelling and pain in these lymph nodes.” ( Paragraph 6)

C.“This results in a prolonged infection and greater lung damage. This can also set the stage for complications including secondary bacterial pneumonia, which can often be deadly.” ( Paragraph 8)
