The process of disinfection eliminates ___

• A. Most microorganisms
• B. All microorganisms
• C. No microorganisms
• D. Some viruses

Answer: (A)

Disinfection reduces the number of microorganisms on inanimate surfaces to safe levels. It lowers the microbial load substantially, especially targeting common pathogens, but it does not guarantee the complete elimination of every microorganism. Some hardy forms, such as certain bacterial spores or resistant viruses, can survive typical disinfection methods, which is why sterilization is required when total eradication is essential. So the best description is that disinfection eliminates most microorganisms, not all.
