Which of the following is a component of a White Russian?

The White Russian is a classic cocktail that primarily consists of three main ingredients: vodka, coffee liqueur, and cream. Coffee brandy, though not traditionally listed among the core ingredients, can sometimes be used as a variation of coffee liqueur to impart a similar flavor profile to the drink. This alternative can provide a unique twist and still evoke the essence of a White Russian, while keeping the coffee flavor prominent.

The other options do not align with the traditional or any recognized variations of a White Russian. Amaretto is a sweet almond-flavored liqueur that would not contribute to the coffee profile of the cocktail. Cranberry juice is fruity and tangy, which does not complement the creamy and coffee flavors of a White Russian. Gin, while a common base spirit in many cocktails, does not belong in a White Russian, which is defined by its use of vodka instead.
