What beverage modification does "SOY" refer to?

The term "SOY" specifically refers to soy milk, which is a popular non-dairy alternative made from soybeans. Soy milk is often used as a substitute for cow's milk in various beverages and recipes due to its creamy texture and nutritional profile, which includes protein comparable to that of dairy milk. It is a favored option for those who are lactose intolerant, allergic to dairy, or following a vegan diet, making it a versatile choice for many customers at coffee shops and cafes.

In relation to the context of the other options, coconut milk, oat milk, and whole milk represent different types of milk alternatives or animal-based milk. Each has its unique flavor, texture, and nutritional content, but they do not align with the term "SOY," which is distinctively linked to soy milk.
