Which of the following syrups can be used in a sugar-free version?

Salted Caramel syrup is available in a sugar-free version, making it suitable for customers who are watching their sugar intake. This aspect is important for accommodating various dietary preferences and health considerations. Sugar-free syrups provide a way to enjoy the same flavors while reducing overall sugar consumption.

Typically, each syrup flavor has a corresponding version that may or may not be sugar-free. While other flavors listed may be popular, they may not offer a sugar-free alternative, thereby limiting options for customers who require or prefer sugar-free choices. Thus, Salted Caramel stands out as the correct response in this context.
