Which term means completely free of any living organisms?

• A. Sterile
• B. Aseptic
• C. Clean
• D. Sanitary

Answer: (A)

Sterile means completely free of any living organisms, including spores. In medical settings, sterilization aims to remove all viable microbes from instruments and environments, which is essential for invasive procedures and implants. Aseptic refers to practices that prevent contamination and strive to maintain a sterile state, but it doesn’t guarantee that every item is free of all organisms at every moment. Clean means there’s no visible dirt, yet surfaces can still harbor microbes. Sanitary describes overall cleanliness and safety but does not require the absence of all microorganisms. So, the term that best matches “completely free of any living organisms” is sterile.
