Which term describes the process that completely destroys all microbial life, including spores?

• A. Sterilization
• B. Disinfection
• C. Antisepsis
• D. Sanitization

Answer: (A)

Sterilization is the process that completely destroys all microbial life, including spores. This level of elimination is achieved with methods like autoclaving (steam under pressure), dry heat, or chemical sterilants that are proven to inactivate spores and other hard-to-kill organisms. Other terms—disinfection, antisepsis, and sanitization—reduce or remove many microbes but do not guarantee the total destruction of spores, which is why they aren’t the correct choice for this description.
