Which of the following best describes Gueuze?

Gueuze is a traditional Belgian beer that is indeed characterized by being a blend of young and old lambics, typically aged for one, two, and three years. This blending process allows for a complex flavor profile and contributes to the beer's unique sourness and effervescence. The young lambic adds freshness and sweetness, while the older lambics introduce depth and a complex, funky character that comes from wild yeast strains naturally present in the environment. The result is a sparkling, tart, and sometimes fruity beer, making the description of it as a blended beer aged over different time periods accurate.

The other choices do not align with the characteristics of Gueuze; it is not a light or hop-forward beer, nor is it a dark beer with roasted flavors, and it typically has a noticeable carbonation level rather than being low-carbonation.
