What flavor corresponds with the letter "B"?

The flavor that corresponds with the letter "B" is Blueberry. In this context, "B" has been designated specifically for Blueberry, which is a popular flavor among Dunkin' products, especially in their muffins and coffees. This choice reflects the brand's long-standing offerings and aligns with customer preferences for fruity flavors.

Banana, while a well-known flavor, does not specifically match the "B" in this context as it could be confused with a different choice. Blackberry is also a valid fruit flavor but is less commonly associated with Dunkin' compared to Blueberry. Biscotti, while a delightful flavor, does not start with the letter "B" that corresponds with the fruity theme usually highlighted in Dunkin's selections for breakfast items or beverages. Understanding the branding and flavor offerings helps clarify why Blueberry is the correct answer in this scenario.
