B Correct answer
Explanation

Autoclaves sterilize using saturated steam under pressure, typically at 121°C for 15-20 minutes. The pressure prevents water from boiling at 100°C, allowing higher temperatures that kill all microorganisms. This method is more effective than boiling water (C) or dry heat (A).
