Final answer:
The chef needs to obtain a variance, which in this context means an c) authorization, to legally sell freshly prepared orange juice in compliance with local food handling regulations.
Step-by-step explanation:
The chef in the operation decides that preparing fresh orange juice and packaging it to sell will increase sales. In order to sell it, she must obtain a variance, which in the context of food service, refers to official permission to deviate from the standard health regulations typically required for food businesses. The correct answer to this question is c) Authorization. Variance in this case is synonymous with authorization, which means the chef must apply for and receive official approval from the relevant health department or food regulation authority before they can legally sell the freshly prepared orange juice. This is necessary to ensure that the product meets safety standards and that the business is complying with local food handling regulations.
