How long must a chemical disinfectant be in use to be effective?

1 minute
10 minutes
5 minutes
30 minutes

The correct answer is: 10 minutes

Chemical disinfectants need to be in use for a sufficient amount of time to effectively kill any harmful microorganisms. 10 minutes is the correct answer because it allows enough time for the disinfectant to properly work and eliminate bacteria, viruses, and other pathogens. Choosing options A, C, or D would not provide enough time for the chemical disinfectant to be fully effective in disinfecting the surfaces.
