How is a mocha typically prepared?

The preparation of a mocha typically involves espresso combined with steamed milk, chocolate syrup or cocoa powder, and is often topped with whipped cream. It is essentially a combination of chocolate and coffee, which contributes to its unique flavor. The correct choice reflects the fundamental elements of a mocha: the base is espresso, which provides the strong coffee flavor, while the addition of chocolate is what defines the drink as a mocha rather than just a coffee.

The option that mentions hot water with dissolved chocolate and coffee doesn't capture the full essence of a mocha. Mocha is distinguished by its creamy texture from the steamed milk, which is essential for balancing the flavors of chocolate and coffee. Therefore, while chocolate is a key ingredient, the preparation process and texture provided by milk are critical for crafting a traditional mocha.
