Answer: B
Explanation: I would say B because the other explanations do not make any sense. They stray away from the topic, and it only makes sense to wash, rinse,and sanitize the cutting board before using it. This it ensures that there are less germs on the cutting board, because the washing rinsing, and sanitizing killed a large portion of those germs. That meaning Juanita wont be making contaminated food.
