Explanation:

The production possibilities frontier (FPP) is a graphic representation of the maximum quantities of production that an economy can obtain in a given period using all the resources it has available.

In an economy that has thousands of products, the alternatives to produce one good or another and how much of each are very large. When an alternative is chosen, it means that other possibilities are being renounced. The relationship between what we choose and what we give up is the opportunity cost.
