What distinguishes a cappuccino from a latte?

A cappuccino is distinguished from a latte primarily by its texture and proportion of milk ingredients. In a cappuccino, there is a significant amount of foam relative to the amount of steamed milk, leading to a creamier and frothier beverage experience. This typically consists of equal parts espresso, steamed milk, and milk foam. Conversely, a latte contains more steamed milk and less foam, resulting in a smoother and creamier drink without the pronounced layer of foam characteristic of a cappuccino.

This difference in texture and milk composition is what truly sets the cappuccino apart from the latte. The other choices either misrepresent the actual differences between these two beverages or make claims that do not align with traditional preparation methods or characteristics.
