Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Prions are infectious agents composed entirely of protein. They are misfolded forms of a normal cellular protein (PrP^C) that can induce other normal proteins to misfold, leading to fatal neurodegenerative diseases like Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy (mad cow disease). They contain no nucleic acid (DNA or RNA).

Hint

These infectious agents are unique for lacking any genetic material like DNA or RNA.
