Which cocktail is garnished with a lime slice?

The correct choice is the Gimlet Martini, which is traditionally garnished with a lime slice. This classic cocktail typically consists of gin and lime juice, and the lime garnish enhances its citrusy flavor and adds a visually appealing element to the drink.

The choice of garnish in cocktails often reflects their ingredients and intended flavor profile. In the case of the Gimlet, the lime complements the botanical notes of the gin, making it a perfect match.

While other cocktails may use various garnishes that suit their flavors or aesthetics, the Gimlet's association with lime is particularly strong due to its foundational role in the cocktail's composition. Therefore, choosing a lime slice as the garnish for this drink reinforces the overall character of the Gimlet, making it the standout choice in this question.
