Final answer:
Tuberculosis is primarily transmitted through inhalation of respiratory droplets or aerosols from an infected person.
Step-by-step explanation:
Tuberculosis is primarily transmitted through inhalation of respiratory droplets or aerosols from an infected person. When an infected person coughs or sneezes, the Mycobacterium tuberculosis bacteria are expelled into the air in small droplets, which can then be inhaled by nearby individuals. This is the most common way tuberculosis spreads.
