Which meal service option requires a variable pricing structure based on selections?

• A. A la carte
• B. Standard
• C. Flat rate
• D. Traditional

Answer: (A)

The a la carte meal service option is designed to allow customers the flexibility to choose individual items from a menu, rather than being limited to a set meal or package. This service model inherently involves a variable pricing structure because each selected item may have a different price attached to it. Customers can customize their meals based on personal preferences and dietary requirements, which is a key feature of a la carte dining.

In contrast, other options like standard, flat rate, and traditional meal services typically involve pre-defined menu selections with fixed pricing or set meal combinations, resulting in less pricing variability. This makes a la carte the correct choice, as it directly aligns with the concept of customization and variability in pricing based on selection.
