WHO hand wash time with soap is:

Correct option is A

· 40 to 60 seconds: WHO specifies that handwashing with soap should last 40 to 60 seconds to cover all steps, including palm rubbing, back of the hand, fingers, and wrists.
· 20 to 30 seconds: 20 to 30 seconds is the recommended duration for using alcohol-based hand rubs, not soap and water.
· 2 minutes: Two minutes is not the standard time recommended by WHO for hand washing; it exceeds the necessary duration for effective cleaning.
· 5 minutes: This is far longer than needed for hand washing and is not practical or recommended in routine practice.
Additional Information:
· Effective handwashing is crucial in infection control, particularly in healthcare settings, and should include thorough cleaning of all hand surfaces.
· Alcohol-based hand rubs are used when soap and water are unavailable but require shorter application times.
