Solution
The correct option is D Prions
Prions are proteinaceous infectious particles that can cause abnormal folding of specific normal cellular proteins leading to disease. Because of their acellular structure and being made-up of only of protein without DNA or RNA, they are extremely resistant to chemicals, heat and radiation.
The rest three - bacteriophages, viroid and virusoids - contain some form of DNA or RNA but prions do not contain any sort of nucleic acids.
