Pathogens can be given off and carried in the air when an infected individual a. comes in contact with another individual b. has an open sore that is bleeding c. coughs or sneezes into the air d. is carried by one host to infect another

The correct answer is C. Coughs or sneezes into the air.

Explanation

When we sneeze or cough without covering our mouths, we are contributing to the spread of pathogens or diseases through indirect contact, that is, a form of spread in which diseases are dispersed in the air, and they are transported there until they find another body. This is realted to  airborne transmission because disease travels or remains suspended in the air for a time in which it can infect other people. For this reason, it is recommended that when we are sick we sneeze and cough by covering our nose and mouth to avoid its indirect transmission. So, the correct answer is C. Coughs or sneezes into the air.
