Which of the following is a type of glassware?

Stemware is a specific type of glassware that is designed for serving beverages and is characterized by a stem that elevates the bowl of the glass above the table. This design not only enhances the aesthetic appeal but also serves a functional purpose; the stem allows the drinker to hold the glass without affecting the temperature of the drink inside. Stemware commonly includes items like wine glasses, champagne flutes, and cocktail glasses, all of which are specially designed for different types of drinks.

Other options like vases, bowls, and plates may be made of glass, but they do not fall under the category of glassware specifically dedicated to holding drinks. Bowls can be a broad category of serving pieces and vases are typically used for holding flowers or decorative purposes, while plates serve as flat dishes for serving food. Thus, stemware uniquely encompasses those glass items specifically used for drinking.
