What is the temperature used for autoclaving?

Correct option is B

Ans. (b)
Sol. Autoclaving is a sterilization method that uses steam under pressure, and the standard temperature used is 121°C maintained for 15–20 minutes at 15 psi pressure. It effectively kills bacteria, viruses, fungi, and spores, making it a preferred method for sterilizing surgical instruments and laboratory materials.
Explanation of each option:
· (a) 101°C – Too low for effective sterilization.
· (b) 121°C – Correct answer. Standard temperature used in autoclaving for effective sterilization.
· (c) 130°C – Higher than needed and not commonly used.
· (d) 125°C – Close, but not the standard; 121°C is widely accepted for general sterilization.
