Which of the following modifications is not associated with a milk type?

The choice indicating "SP" represents a modification that is not explicitly linked to a specific milk type. In the context of the beverage industry, especially within coffee and specialty drinks, modifications typically refer to various non-dairy alternatives or milk types like oat and soy. Oat milk and soy milk are well-known substitutes for traditional dairy milks, widely used for their unique flavors and textures in beverages.

On the other hand, "SP" does not refer to a standard milk type; instead, it could stand for something like "sugar-free" or "special preparation," which are general modifications rather than specific dairy or non-dairy milks. Therefore, it is clear that "SP" does not fit into the category associated specifically with milk types, making it the correct choice for this question.
