Why the other options are wrong
- A. 30 minutes is excessive and not typically required for standard disinfection practices.
- C. 5 minutes may be sufficient for some sanitizers, but not the minimum for disinfection in California barbering.
- D. 1 minute is generally too short for effective disinfection of non-porous surfaces.
