Which of the following is a type of American whiskey?

Bourbon is indeed a type of American whiskey, and its production must adhere to specific regulations set forth by law. To be classified as bourbon, the whiskey must be made from a grain mixture that is at least 51% corn, aged in new charred oak barrels, and distilled to no more than 160 proof. Additionally, it must be entered into the barrel for aging at no more than 125 proof and be bottled at 80 proof or higher.

This distinctiveness sets bourbon apart from other types of whiskey, such as rye, which also qualifies as an American whiskey but is primarily made from rye grain rather than corn. While scotch is a whiskey from Scotland and tequila is a distilled beverage made from the agave plant typically associated with Mexico, bourbon's uniqueness lies in its ingredients and the production process, which are defined by American law.
