Question

if all proper hand washing steps are followed, how long should the entire process take? at least 20 seconds, at most 2 minutes, at least 60 seconds, at most 30 seconds

Explanation:

Proper handwashing steps (like wetting, lathering, scrubbing, rinsing, drying) are recommended to take at least 20 seconds for effective hygiene, as per health guidelines (e.g., CDC recommendations). The other options (at most 2 minutes is too long for basic handwashing, at least 60 seconds is excessive, at most 30 seconds may not be enough) don't align with standard handwashing time recommendations.

Answer:

A. At least 20 seconds
