When aerosols containing pathogens spread disease from a distance of less than one meter, it is considered

A) waterborne transmission.

B) airborne transmission.

C) vector transmission.

D) contact transmission.

b) contact transmission.

Explanation:

Contact transmission of pathogens occurs directly or indirectly between the source of the pathogens and the host organisms. During contact transmission by droplet spread, the pathogen is carried on smaller particles. These particles move through air for a very short distance, usually less than a meter. Therefore, droplet transmission of a pathogen requires that the source and host are present in close proximity.
