1. 5 seconds

2. 10 seconds

3. 15 seconds

4. 30 seconds

The correct answer is: 15 seconds

The recommended duration for lathering hands with liquid antibacterial soap during hand washing is 15 seconds. This time frame is based on guidelines from health authorities, which emphasize that adequate lathering is necessary to effectively remove dirt, bacteria, and viruses from the skin. During hand washing, it is essential to cover all surfaces of the hands, including between the fingers, under the nails, and around the wrists. Lathering for at least 15 seconds ensures that the soap has enough time to interact with contaminants and effectively lift them away from the skin, particularly when using antibacterial soap, which is designed to eliminate or reduce harmful microorganisms. While shorter durations might seem sufficient, they often do not provide enough time for the soap to work effectively, thus risking incomplete cleansing. Longer durations, such as 30 seconds, while thorough, may not be necessary in all situations if proper technique is employed for at least 15 seconds.
