Answer:
Option B, bacteria
Explanation:
The pulmonary condition known as tuberculosis (TB) is an infectious disease caused when a bacteria known as Mycobacterium tuberculosis gains entry to the patient's lungs via aerosolized droplets from a person with active TB, such as from a cough, a sneeze, or simply speaking.
Fortunately, TB can be treated with a full course of antibiotics, unless the patient is infected with a drug-resistant strain, and it is currently vaccine-preventable, though this vaccine is not necessarily administered in the United States because TB is not endemic to the country.
