Which of the following drinks is a Mint Hot Coco?

The designation "MHC" stands for Mint Hot Coco. In the context of Dunkin Donuts' drink codes, the letters typically represent the type of beverage along with its flavor profile or any additional ingredients. "M" is commonly used to signify a flavor and "HC" indicates Hot Chocolate. When combined, they create "MHC," which specifically identifies Mint Hot Coco.

The other options do not accurately convey the combination of mint and hot chocolate flavors. "MH" could imply something related to mint hot beverages, but it lacks the specificity of hot chocolate. "MHCY" includes an additional letter that does not align with the standard abbreviations used at Dunkin Donuts, and "MC" is far too generic and does not correspond to any known drink in their lineup. Understanding these codes helps ensure correct drink orders and enhances customer service efficiency.
