Answer:
B: Demonstrating proper cooking temperatures
Step-by-step explanation:
Demonstrating proper cooking temperatures falls under the responsibility of the manager. The manager has other duties to perform, but the most important one is observing the health and sanitation rules.
The manager is the general overseer, and does not have time to micromanage every part of the business, such as follow a cleaning schedule for the dining room or notifying costumers of problems in the kitchen. It is to his/her credit if they know the liquor laws, however he/she can delegate that responsibility to another employee.
