• A. The most important part of personal hygiene; 100 degrees and 15 to 20 seconds
• B. Optional step
• C. Wash with cold water for 5 seconds
• D. Only required after handling raw meat

Answer: (A)

Regular handwashing is the most effective way to remove germs and prevent contamination. For correct technique, use warm running water around 100°F with soap and scrub all hand surfaces for about 15 to 20 seconds, then rinse and dry with a clean towel. This duration and temperature ensure dirt and microbes are lifted from the skin rather than just rinsed away, making the process reliable. Shorter times or cold water don’t clean as thoroughly, and handwashing isn’t only needed after handling raw meat—it's important before handling food, after using the restroom, and after touching dirty surfaces.
