Final answer:
The correct order from most resistant to antimicrobial agents to least resistant to antimicrobial agents is: II, V, I, IV, III.
Step-by-step explanation:
The correct order from most resistant to antimicrobial agents to least resistant to antimicrobial agents is: II, V, I, IV, III.
Bacterial endospores are the most resistant to antimicrobial agents due to their thick protective coat.
Protozoan cysts are less resistant than bacterial endospores, but more resistant than other organisms.
Protozoa are less resistant than protozoan cysts, followed by non-enveloped viruses which are less resistant than protozoa.
Finally, enveloped viruses are the least resistant to antimicrobial agents.
