Detailed explanation-1: -Answer and Explanation: The only statement that is not true regarding protists is c) They are prokaryotic, as bacteria and archaea are. Since protist cells contain membrane-bound organelles and true nuclei, they are classified as eukaryotic cells.
Detailed explanation-2: -Some severe diseases of humans are caused by protists, primarily blood parasites. Malaria, trypanosomiasis (e.g., African sleeping sickness), leishmaniasis, toxoplasmosis, and amoebic dysentery are debilitating or fatal afflictions.
