Final answer:C. Portal of ExitThe Portal of Exit is the link in the chain of infection in this scenario, which is represented by Michael's respiratory droplets when he coughs and sneezes.Explanation:In the given scenario, Michael is coughing and sneezing due to an infection in his sinuses and lungs, and he only covers his nose and mouth about half the time. The link in the chain of infection that places others at risk of contracting the infection is the Portal of Exit. Specifically, the respiratory droplets that Michael emits when he coughs or sneezes without covering his nose and mouth serve as the portal of exit for the pathogens. These expelled droplets can cause direct droplet transmission to others nearby or contaminate surfaces, which others may touch and then introduce the pathogens into their own bodies through their mouth, nose, or eyes....
