What does the concept of opportunity cost represent in the context of a Production Possibility Curve (PPC)?

Opportunity cost is the value of what you give up when you choose one option over another. In the context of a Production Possibility Curve (PPC), it shows the trade-off between two different goods or services that a society can produce. When you move along the curve to produce more of one good, you must reduce the amount of the other good produced, which represents the opportunity cost. For example, if a country decides to produce more cars instead of computers, the opportunity cost is the number of computers that could have been made instead. This concept helps us understand the limits of production and the choices we must make in resource allocation.
