Sterilization is defined as which of the following?

• A. Disinfection
• B. Sanitization
• C. Asepsis
• D. Complete killing of all microorganisms

Answer: (D)

Sterilization means the complete destruction or elimination of all microorganisms, including bacterial spores, on a surface or in a substance, achieved by methods such as steam under pressure, dry heat, chemical sterilants, or irradiation. This full kill distinguishes it from other terms: disinfection reduces most pathogens but may not kill all microorganisms or spores; sanitization lowers microbial numbers to safe levels; asepsis refers to a state or practice that prevents contamination, not the process itself. Therefore, sterilization is defined by the complete killing of all microorganisms.
