Answer: (C)

The correct order for hand-washing is crucial for effectively removing germs and preventing the spread of illness. The sequence starts with wetting the hands or arms to ensure that the soap can work properly; soap needs water to create the lather necessary for cleaning. Next, applying soap is essential, as it contains surfactants that lift dirt, grease, and pathogens off the skin.

Following the application, scrubbing for 10-15 seconds is critical. This duration is recommended because it allows sufficient time for the soap to break down and fully remove contaminants. Lathering and scrubbing the surfaces of the hands, including between fingers and under nails, enhances the removal of harmful microorganisms.

After scrubbing, rinsing thoroughly is necessary to wash away both the soap and the germs that have been loosened during the scrubbing process. The final step is to dry the hands, which can be accomplished using a clean towel or air dryer. Proper drying is significant because germs can spread more easily from wet surfaces.

This sequence—wetting, applying soap, scrubbing, rinsing, and drying—ensures that the hand-washing process is both effective and hygienic, significantly reducing the risk of illness transmission.
