Which of the following drinks is classified as a refillable beverage?

A refillable beverage is one that customers can request multiple servings of at no extra charge. Water is typically classified as a refillable beverage in many dining establishments, including Cracker Barrel, because it is generally provided for free. Customers often appreciate having access to unlimited water refills, especially during meals.

In contrast, options such as juice and milk are usually offered at a fixed charge and are not typically refillable, meaning customers would have to pay for additional servings. Bottled soda is sold as a single-serving product and is not served in a manner that allows for refills, making it non-refillable as well. Thus, water stands out as the correct answer because it aligns with the common practice of allowing unlimited refills at no cost.
