Airborne pathogens are primarily transmitted through the air, which is why the correct answer is air. This mode of transmission involves tiny droplets or aerosolized particles that are expelled into the environment when an infected person coughs, sneezes, or talks. These droplets can remain suspended in the air for extended periods and can be inhaled by individuals who are not infected, thus facilitating the spread of diseases.

In contrast to airborne transmission, contact transmission refers to the transfer of pathogens through physical touch, which is common with surface or skin contact. Food transmission involves the ingestion of pathogens through contaminated food products, while water transmission relates to pathogens spread through contaminated water supplies. These modes of transmission do not effectively convey how airborne pathogens spread, emphasizing the distinct nature of airborne transmission as the primary method for this category of pathogens.
