... Answer is C). Prions  

Prion is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease ( CJD ) in humans. The word itself derives from 'proteinaceous infectious particle' ; it refers to " the initially heretical hypothesis that the infectious agent causing those diseases consists only of protein, with no nucleic acid genome. The prion hypothesis explained why the mysterious infectious agent is resistant to ultraviolet radiation, which breaks down nucleic acids, but is susceptible to substances that disrupt proteins.
