What distinguishes a CFA Sandwich from a CFA Deluxe?

A CFA Sandwich is commonly known for its simple composition, typically featuring a chicken filet with pickles on a toasted bun. In contrast, a CFA Deluxe elevates the basic sandwich by adding fresh toppings such as tomato, lettuce, and cheese. This additional layer of ingredients is what distinctly differentiates the Deluxe from the standard sandwich, enhancing its flavor and texture profile.

The size of the sandwich, the number of chicken filets, and the type of bread are not the primary factors that distinguish between these two offerings, as both sandwiches are generally equivalent in size and type of bread. The key distinction lies in the Deluxe version's inclusion of fresh vegetables and cheese, making option B the correct choice.
