The bacteria present in the (blank) of the person infected with tuberculosis are spread when the person coughs, sneezes, speaks, or sings.

Saliva
Blood
Urine
Airborne droplets

The correct answer is: Airborne droplets

The correct answer is airborne droplets because tuberculosis (TB) is primarily transmitted through the respiratory droplets that are expelled into the air when an infected person coughs, sneezes, speaks, or sings. These tiny droplets can remain suspended in the air and can be inhaled by others, leading to the spread of the bacteria that cause TB. This transmission process highlights the importance of infection control measures, such as proper ventilation and wearing masks, to prevent the spread of tuberculosis in community and healthcare settings. Other bodily fluids such as saliva, blood, and urine do not play a significant role in the transmission of TB, making them less relevant in this context.
