• A. 10 seconds
• B. 15 seconds
• C. 20 seconds
• D. 30 seconds

Answer: (C)

The recommended minimum handwashing time to effectively remove germs is 20 seconds. This duration has been endorsed by health authorities, including the Centers for Disease Control and Prevention (CDC), as it allows sufficient time for soap to break down the oils and dirt on the skin, which can harbor pathogens. During this time, individuals are encouraged to scrub all parts of their hands thoroughly, including between the fingers, under the nails, and around the wrists, to ensure that all surfaces are cleaned.

Shorter durations, such as 10 or 15 seconds, may not provide enough time to effectively cleanse the hands, potentially leaving germs behind. A full 30 seconds may be more thorough but is generally considered more than necessary for effective handwashing under normal circumstances. Aim for the balance of 20 seconds, making it practical and achievable for regular hand hygiene.
