Which cocktail uses gin, tonic water, and a lime wedge?

The cocktail that uses gin, tonic water, and a lime wedge is the gin and tonic. This classic drink is known for its refreshing qualities and is typically enjoyed as a light beverage. The combination of gin and tonic water creates a balanced flavor profile, where the botanicals in the gin are complemented by the effervescence and slight sweetness of the tonic. The lime wedge adds a zesty twist, enhancing the overall taste and brightness of the drink.

Other cocktails, such as the vodka tonic, contain a similar base ingredient, but substitute gin for vodka, making them distinctly different. The mojito is a rum-based drink featuring mint, lime, and sugar, which bears no resemblance to the flavor profile of a gin and tonic. Lastly, a Dark and Stormy is a rum-based cocktail that includes ginger beer and lime juice, further diverging from what makes a gin and tonic unique. The elements of gin, tonic, and lime specifically define the gin and tonic, establishing it as the correct answer.
