## **Core Concept**
Prions are infectious proteins that cause fatal neurodegenerative diseases in animals, including humans. They are unique in that they do not contain nucleic acids (DNA or RNA) and are highly resistant to inactivation. The core concept here revolves around the nature of prions and the methods required to inactivate them.

## **Why the Correct Answer is Right**
The correct answer, , involves the use of certain chemicals or processes that can inactivate prions. Prions are notoriously difficult to kill because they are not living organisms and do not contain genetic material. Autoclaving with sodium hydroxide or using specific enzymatic treatments can disrupt prion proteins, making them non-infectious.

## **Why Each Wrong Option is Incorrect**
- **Option A:** . This option might involve common methods for sterilization or inactivation of pathogens, but prions require more specific treatments due to their unique nature.
- **Option B:** . This could involve radiation or other methods that might not be effective against prions due to their proteinaceous nature and lack of nucleic acid.
- **Option C:** . Similar to option A, this might not specifically target prions effectively.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that prions are highly resistant to conventional sterilization methods, including heat, radiation, and chemicals. This makes decontamination of equipment and environments where prion-infected materials have been handled extremely challenging.

## **Correct Answer:** .
