Which term describes a surface or environment free from contamination?

• A. Aseptic
• B. Contaminated
• C. Hygienic
• D. Polluted

Answer: (A)

Aseptic describes a surface or environment that is kept free from contamination by microorganisms. In medical and lab settings, asepsis means preventing any microorganisms from contaminating a area or instrument, typically through sterile technique, cleaning, and proper handling. This is why it’s the best term for something described as free from contamination. Hygienic means clean or sanitary but doesnt guarantee that all microorganisms are absent. Contaminated or polluted clearly indicate the presence of contaminants. Sterile would be absolutely devoid of any microorganisms, but aseptic best captures the idea of being free from contamination in everyday clinical contexts.
