Which of the following is a type of bean, nut, or seed liqueur?

The correct answer is Kahlua, as it is a coffee liqueur made primarily from sugarcane rum, coffee beans, vanilla bean, and other flavorings. This categorizes it within the realm of bean, nut, or seed liqueurs because it incorporates coffee beans as a key ingredient, which is derived from seeds.

In contrast, Amaretto is an almond-flavored liqueur, primarily made from apricot pits or nuts, but its primary flavor comes from almonds, moving it into a different category. Campari is an aperitif known for its bitter flavor and is typically made from a secret mix of herbs and fruits rather than beans, nuts, or seeds, focusing more on botanical elements. Chartreuse is a herbal liqueur made from a variety of herbs and plants, whole consuming the essence of natural botanicals, rather than specifically nuts, seeds, or beans.
