UV sterilisation is described as what kind of method?

• A. Conventional
• B. Destructive
• C. Versatile
• D. Limited

Answer: (C)

UV sterilisation uses ultraviolet-C light to inactivate microorganisms by damaging their DNA, so it cleans without heat or chemicals. This makes it versatile because it can be applied to air, water, and surfaces, and it can be used in enclosed chambers, integrated into equipment, or used as a handheld or installation option. Its ability to work across different contexts and materials, with quick, residue-free action, is what makes it describe as versatile. It’s not the same as conventional steam or chemical methods, and it doesn’t inherently destroy the items being sterilized, though it does have limitations such as needing direct exposure without shadows and being less effective on shaded or opaque areas.
