The correct answer emphasizes the importance of lathering the soap on your hands for a full 20 seconds, which is crucial for effectively removing dirt, bacteria, and viruses. When hands are wet and soap is applied, it initiates the cleaning process. Scrubbing increases the friction and helps dislodge pathogens from the skin's surface.

Lathering for 20 seconds allows the soap to work effectively, creating a good amount of foam that helps to break down oils and debris, ensuring a more thorough clean. After lathering, rinsing with clean water removes the soap and any loosened particles from the hands, followed by drying, which is important because bacteria can transfer more readily to and from wet surfaces.

In contrast, simply scrubbing for 10 seconds is insufficient because it does not provide enough time for the soap to properly clean the hands.
