Answer:
D. One person's benefit from the good does not reduce the benefit available to other people.
Step-by-step explanation:
A product (good) can be defined as any physical object or material that typically satisfy and meets the demands, needs or wants of customers. Some examples of a product are mobile phones, television, microphone, microwave oven, bread, pencil, freezer, beverages, soft drinks etc.
According to the economist Philip Kotler in his book titled "Marketing management" he stated that, there are five (5) levels of a product. This includes;
1. Core benefit.
2. Generic product.
3. Expected product.
4. Augmented product.
5. Potential product.
The core benefit of a product can be defined as the basic (fundamental) wants or needs that is being satisfied, met and taken care of when a customer purchase a product.
A non-rivalrous product (good) is one in which a person's (buyer's) benefit from through the purchase of a good does not reduce or annul the benefit available to other people.
