Nutritional labeling requirements apply to food made on-site when the food is:

Nutritional labeling requirements are primarily established to ensure that consumers receive important information regarding the foods they purchase, which helps them make informed choices about their diets. When it comes to foods that are packaged and sold on retail display shelves, these items fall under specific labeling regulations set by authorities like the FDA (Food and Drug Administration).

Packaged food products intended for sale to consumers must include nutritional information on their labels. This requirement applies because such products are not made in a controlled setting where they can be monitored closely by food safety managers and are ready for consumption in their packaged form. The label provides essential nutrition facts, ingredients, and allergen information, which is vital for consumers.

In contrast, the other options refer to food preparations that may not require nutritional labeling due to their transient nature (like daily prepared self-service items or food made for individual servings or take-out). These items might be exempt from such labeling requirements because they are either made fresh for immediate consumption or do not meet certain packaging criteria laid out by regulatory agencies. Therefore, the correct answer identifies the scenario where nutritional labeling is mandated due to the product's retail-ready status.
