The correct answer is **D opportunity cost**.

When a country moves along its production possibility curve (PPC), it means that it is reallocating resources to produce more of one good at the expense of another. This trade-off reflects the opportunity cost, which is the value of the next best alternative that is foregone when resources are used for a specific purpose.
