Answer:
The correct answer is option C.
Explanation:
The production possibility curve shows the maximum possible bundle of two goods that can be produced using all the available resources and state of technology.
Since the resources are scarce, when we produce more of one good, we need to sacrifice more and more of the other good.
If all the resources in the economy are fully employed then it is not possible to increase the production of one good without decreasing the production of the other.
The economy can thus produce either on the production possibility curve or below it but not above it.
