Answer:
D. Report to the manager when you are sick
Explanation:
According to my research on food safety drills, I can say that based on the information provided within the question the most important responsibility is to report to the manager when you are sick. This is done in order for the manager to decide whether he can put you to work elsewhere away from the food so you do not contaminate the food and in term the people, or send you home for the day.
