What is the primary restriction of a class 4 license?

The primary restriction of a class 4 license is that it allows for retail sales but only in original packaging. This means that any alcoholic beverages sold under this license must remain sealed in their original containers until they are purchased. This restriction is intended to ensure that the products are not tampered with and are sold as intended by the manufacturer, maintaining standards of quality and safety for consumers.

The option about selling beer only is too narrow and does not encompass the broader range of alcoholic beverages that may be included under a class 4 license. The option regarding sales to anyone regardless of age is fundamentally incorrect since all alcoholic beverage sales are subject to age restrictions. Finally, the choice about being valid only in designated areas does not accurately reflect the nature of the license, as class 4 licenses can be used at various retail locations as long as they comply with the outlined regulations. Thus, the focus on original packaging in the correct choice encapsulates the key restriction that must be understood.
