Which group includes other disease-causing microorganisms such as fungi, parasites, and prions?

• A. Fungi
• B. Parasites
• C. Prions
• D. Fungi, Parasites, Prions

Answer: (D)

Disease-causing microorganisms come in several forms beyond bacteria and viruses. Fungi are living organisms that can invade tissues and cause infections; parasites (protozoa and helminths) live in or on a host and produce disease; prions are infectious proteins that propagate by misfolding normal proteins, leading to serious neurodegenerative diseases. Together, these represent the broad category of disease-causing agents. The option that lists all three groups correctly identifies the set that includes fungi, parasites, and prions, making it the best choice.
