What is a method of sterilization?

  1. Washing with soap and water

  2. Using chemical disinfectants

  3. Autoclaving with high-pressure steam

  4. Rinsing with hot water

The correct answer is: Autoclaving with high-pressure steam

Autoclaving with high-pressure steam is the most effective method of sterilization compared to the other options. Although washing with soap and water and rinsing with hot water may remove some microorganisms, they are not considered proper methods of sterilization. Using chemical disinfectants may kill some microorganisms but may not be as effective as autoclaving. Autoclaving with high-pressure steam involves subjecting materials to high temperatures and pressure, effectively killing all microorganisms present. This method is commonly used in medical and laboratory settings to ensure complete sterilization of equipment and instruments.
