Final answer:
The American plan is the hotel pricing structure in which the price of the meal is included in the guest room rate.
Step-by-step explanation:
The correct term that describes the hotel pricing structure in which the price of the meal is included in the guest room rate is the American plan (B).
In the American plan, guests pay a fixed rate for their room which includes all meals. This type of pricing structure is commonly found in resorts or luxury hotels where meals are an important part of the guest experience.
For example, if a guest stays at a hotel with the American plan, they would have breakfast, lunch, and dinner included in the room rate. They wouldn't have to pay separately for each meal.
