Which of the following can be used for antimicrobial action?

• A. Radiation
• B. Disinfectant
• C. Germicide
• D. All of the above

Answer 1

Answer: (D)

All of the above

• Antimicrobial action is defined as to sterilize any substance or vessel by killing off any kind of microorganism that is present on the surface of the substance.
  
• Radiation is the method where ultraviolet rays are used for disinfecting vessels or chemicals that can't be sterilised by heating or other method. It kills the microorganisms as it is mutagenic for the organisms and it breaks the bonds in the microbial DNA which disables or kills it.
  
• Disinfectant and germicide are the chemicals such as phenol, ethanol, formaldehyde that are used to kill bacteria and other disease causing microorganisms.
• So, the correct answer is 'All of the above'
