Which of the following beverages is a blend of different fruits and has a youthful appeal?

The correct choice is Youthberry. This beverage is specifically crafted to appeal to a younger demographic, showcasing a delightful fusion of various fruit flavors. Its blend incorporates hints of tropical fruits and berries, which not only provides a refreshing taste but also aligns with contemporary trends favoring vibrant, fruity beverages.

In contrasts to the other options, Citrus Green Tea Latte combines tea with citrus flavors, which may not directly embody a youthful essence. The Pineapple Kona Pop is a different product primarily known for its pineapple flavor, making it less of a multifruit beverage. Similarly, Mango Black focuses on the mango flavor profile and does not encompass the wider blend approach that defines Youthberry. Thus, Youthberry stands out as a product distinctly characterized by its diverse fruity blend and its attractive appeal to younger customers.
