Which of the following best explains the term "extra shot" in relation to drinks?

The term "extra shot" in relation to drinks typically refers to an additional serving of a particular ingredient, most commonly espresso in coffee beverages or additional spirits in alcoholic drinks. This means that when a patron orders a drink and requests an extra shot, they are asking for more of that specific ingredient to enhance the volume or intensity of their drink.

While considering the context of the other options, the idea of increased price may be associated with an extra shot, as it often results in a higher cost; however, this is not the defining characteristic of what the term means. Similarly, a different drink option does not align with the concept of an extra shot, as it implies a change in the drink rather than an augmentation of the existing ingredients. Finally, the notion of dilution of flavor contrasts with the idea of an extra shot, because the purpose of adding an extra shot is generally to enhance or strengthen the flavor, not dilute it. Thus, the correct interpretation of "extra shot" emphasizes the addition of a specific ingredient to elevate the drink experience.
