What tea does the option "KF" stand for?

The option "KF" stands for "Keep fit," which aligns with a tea that is often positioned as healthy and wellness-focused. In the context of beverage offerings, "Keep fit" suggests a product that promotes health benefits, possibly involving ingredients known for their positive impact on fitness and well-being. This aligns with the trend in the beverage industry toward creating drinks that support a healthy lifestyle, appealing to health-conscious consumers.

The other options, while potentially relevant in different contexts (like Kombucha fizz being a popular fermented drink or Key lime fizz suggesting a refreshing flavor profile), do not specifically connect to a defining characteristic of a tea product known for wellness or fitness. Additionally, "Kid's favorite" may imply a target audience rather than a focus on the health properties that "Keep fit" would signify.
