TB is typically transmitted by airborne droplets.

• A. False
• B. Only through direct contact
• C. True
• D. Only in enclosed spaces

Answer: (C)

The main idea here is how TB is spread. Tuberculosis is transmitted when an infectious person with active pulmonary TB releases tiny airborne particles into the air—droplet nuclei—through coughing, sneezing, or talking. These small particles can linger in the air and be inhaled by others, leading to infection, especially in settings with poor ventilation. That’s why this statement is true: TB is typically transmitted by airborne droplets (aerosols).

The other options don’t fit because TB isn’t spread by just touching someone or by surfaces, and while risk is higher in enclosed or poorly ventilated spaces, it isn’t limited to enclosed spaces alone.
