What beverage type is indicated by "MIS"?

The term "MIS" is a shorthand notation often used in the coffee industry to refer to "Misto." A Misto is a beverage that combines brewed coffee with steamed milk, creating a drink that's similar to a latte but has a different coffee-to-milk ratio. The usage of this abbreviation helps baristas communicate specific drink orders quickly and efficiently.

The other choices present different beverage types: "Milk" references a general dairy product, "Steamer" is typically a child-friendly drink consisting of steamed milk without coffee, and "Lemonade" is a completely different category of beverage not related to coffee at all. Thus, "MIS" points directly towards "Misto," connecting the abbreviation specifically to this popular coffee drink.
