Which juice option includes a combination of tomato and clam?

The correct answer, Clamato, refers specifically to a beverage that combines tomato juice and clam broth. This unique blend is commonly used in cocktails, such as the classic Caesar, which is popular in Canadian cuisine, and is recognized for its savory and slightly briny flavor profile. Clamato's formulation makes it distinct from the other juice options listed, as they do not contain any clam components. Cranberry juice, pineapple juice, and lemonade are all fruit-based options that lack the tomato and clam combination that defines Clamato. This highlights Clamato as the only choice that accurately fits the description provided in the question.
