TB transmission occurs primarily through which action?

Explanation:
TB is spread through the air when an infected person with active pulmonary TB coughs, releasing tiny particles that contain the bacteria. These droplet nuclei can linger in the air and be breathed in by others, leading to new infections. The act of coughing forces a large amount of air and these small particles out, making coughing the most efficient and common way TB is transmitted. While sneezing, speaking, or shouting can also release infectious particles, coughing produces more aerosols and spreads them more widely and quickly, which is why it’s considered the primary transmission action.
