Question

Which of the following statements about autoclaving is TRUE?
Options
A It is effective for destroying prions.
B It requires a temperature of 160°C for 2 hours.
C It is considered the 'gold standard' for sterilisation and destroys endospores.
Correct Answer
D Verification is typically done using membrane filtration.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Autoclaving is the 'gold standard' for sterilisation, effectively destroying all life, including endospores. Prions are NOT reliably destroyed by standard autoclaving, and membrane filtration is a separate sterilisation method. 160°C for 2 hours refers to dry heat sterilisation.

Hint

Recall the specific temperature, pressure, and time associated with standard autoclaving, and its overall efficacy.
