Which of the following diseases is caused by a protozoan?

• A. Influenza
• B. Ebola
• C. Amebic dysentery
• D. Smallpox

Answer: (C)

Amebic dysentery is caused by a protozoan known as Entamoeba histolytica. This organism infects the intestines and can lead to severe diarrhea, stomach pain, and other gastrointestinal issues. Protozoans are single-celled eukaryotic organisms, and their classifications help in understanding the type of diseases they can cause. In contrast, influenza is caused by a virus, which is not classified as a protozoan. Ebola, caused by the Ebola virus, also falls into the viral category. Smallpox is a viral disease caused by the variola virus. Each of these diseases, while important to recognize within the context of infectious diseases and human health, is not caused by protozoa, thus differentiating amebic dysentery as the correct choice in this question.
