b. a person lacking effective resistance to a particular organism
c. microorganisms with the ability to cause infection
d. an opening allowing the microorganism to enter the host
e. location where microorganisms live and can survive, thrive and reproduce

draw a line from the examples to the link in the chain it falls under.

Explanation:

1. An infectious agent is a microorganism that can cause infection. C matches this description.
2. A reservoir is where microorganisms live, thrive and reproduce, so E is the match.
3. The portal of exit is the path by which a pathogen leaves its host, so A is correct.
4. The mode of transmission is how the microorganism moves from one place to another, so F is the match.
5. The portal of entry is an opening for the microorganism to enter the host, so D is correct.
6. A susceptible host is a person lacking effective resistance to a particular organism, so B is the match.
