Answer :
Final answer:
The best answer to the question about how pathogens are transmitted through the air is that they are expelled when an infected individual coughs or sneezes. This airborne transmission allows pathogens to reach and infect other individuals nearby. Understanding this method of transmission is crucial for controlling the spread of respiratory diseases.
Explanation:
Understanding Airborne Transmission of Pathogens
Pathogens can be transmitted through the air when an infected individual coughs or sneezes. When droplets that contain these pathogens are expelled from the respiratory system, they can then be inhaled by nearby individuals.
This method of transmission is particularly relevant for diseases such as the flu and the common cold. Unlike physical contact or having an open sore, airborne transmission can lead to widespread infections because the infected droplets can travel distances and remain suspended in the air for a time.
Best Answer Choice
Given the options provided, the best answer is C. coughs or sneezes into the air. This highlights the typical route through which many pathogens spread, facilitating new infections among those who are exposed.
