Which of the following is considered a fermented beverage?

Wine is considered a fermented beverage because it is produced through the fermentation process of grape juice. During fermentation, yeast converts the sugars present in the grapes into alcohol and carbon dioxide. This process not only produces the alcohol content found in wine but also contributes to the development of its flavors and aromas. The fermentation of various fruits, primarily grapes in this case, is a fundamental aspect of winemaking and distinctly characterizes it as a fermented beverage.

Options such as soda, water, and fruit juice do not undergo fermentation. Soda is a carbonated soft drink that typically includes carbonated water, sweeteners, and flavorings but does not contain alcohol. Water is a pure substance without fermentation processes. While fruit juice comes from squeezing fruits, it is not fermented unless yeast or bacteria are intentionally introduced to promote fermentation, which would shift it towards potential fermentation but does not categorize all fruit juice as a fermented beverage. Hence, wine is the only correct answer in this context.
