Question

cholera, giardiasis, and typhoid fever are all diseases associated with what class of water pollution? super-oxygenated radioactive infectious agents explosive

Explanation:

Cholera is caused by the bacterium Vibrio cholerae, Giardiasis by the protozoan Giardia lamblia, and Typhoid fever by the bacterium Salmonella Typhi. These pathogens are infectious agents (like bacteria, protozoa) that contaminate water. Super - oxygenated water isn't a pollution class causing these diseases, radioactive pollution involves radioactive substances (not related to these pathogens), and explosive pollution is not a relevant water pollution class for these diseases. So the correct option is the one related to infectious agents.

Answer:

C. Infectious agents
