Which of the following is not a type of microorganism?

Explanation:
Microorganisms are tiny living entities that include bacteria, viruses, and parasites. A red blood cell, on the other hand, is a human cell that travels in the bloodstream. It does not live or reproduce on its own and is part of the body’s own tissues, not a microbe. That’s why it’s not considered a microorganism. Bacteria are single-celled microbes capable of living independently; viruses are much smaller particles that must hijack a host cell to replicate; parasites can be single-celled or multicellular organisms that live on or in a host.
