Beer is a non-distilled alcoholic beverage produced by yeast through fermentation. During the fermentation process, yeast converts the sugars in grains (like barley) into alcohol, which is then left to ferment and mature, creating beer.
On the other hand, brandy, rum, and whisky are distilled alcoholic beverages, meaning that after fermentation, the liquid is heated to separate alcohol from other compounds.
Thus, the correct answer is Beer.
