What are the ingredients in the bulk frozen mix?

The correct choice highlights the specific ingredients used in the bulk frozen mix, which consists of Margarita Sour, Finest Call Agave Nectar, Dorado Gold Tequila, and Water. This combination is essential because it reflects both the authentic flavors associated with a high-quality margarita and the sweetening aspect provided by the agave nectar, which enhances the overall taste profile. The Margarita Sour provides the tangy flavor typical of a margarita, while the tequila forms the base spirit essential for this cocktail. Water is included to achieve the desired consistency and flavor balance.

Other ingredient combinations presented in the options do not accurately represent the traditional or intended recipe for a bulk frozen mix at Texas Roadhouse, as they may include spirits or mixers that are not part of their specific formula for margaritas, thus deviating from the standard offerings that customers expect. Therefore, option B stands out as it encapsulates the expected and authentic ingredients that define the signature drink.
