B

D
Portal of entry
Verified step by step guidance1
Understand the chain of infection, which consists of six links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.
Recognize that personal protective equipment (PPE) is designed to create a barrier that prevents pathogens from entering the body.
Identify that PPE primarily blocks the 'portal of entry' by protecting mucous membranes, skin, and respiratory pathways from exposure to infectious agents.
Note that while PPE may indirectly affect other links, its main function is to stop pathogens at the point where they would enter a new host.
Conclude that the link in the chain of infection broken by PPE is the 'portal of entry'.
