The process used to destroy all microbial life including endospores is called:

• A. Sterilization
• B. Pasteurization
• C. Disinfection
• D. Sanitation

Answer: (A)

Sterilization is the process that aims to destroy all microbial life, including endospores, on an object or surface. Endospores are among the most resilient forms of life, so achieving true sterilization requires sporicidal conditions—such as steam under pressure (autoclaving) at high temperature and sufficient time, or other methods that deliver enough heat, potent chemical sterilants, or irradiation. This level of destruction is why sterilization is used for items that must be completely free of viable organisms, like surgical instruments and sterile pharmaceutical products. In contrast, pasteurization lowers the overall microbial load but does not kill spores; disinfection removes many pathogens but may not eliminate spores; and sanitation reduces general contamination to safe levels without achieving sterility.
