In the context of a production possibility curve (PPC), why is a point labeled "F" inside the curve considered an inefficient point, and a point labeled "G" outside the curve considered unattainable?

A) Point F represents an allocation where resources are fully and efficiently utilized, while point G represents an achievable future goal with current resources.
B) Point F indicates that more of one or both goods can be produced without sacrificing the production of any other good, making it inefficient. Point G is unattainable with current resources and technology, suggesting it's beyond the economy's production capabilities.
C) Point F is the most efficient point on the curve, maximizing the production of all goods. Point G represents underutilization of resources and is easily attainable with effort.
D) Both points F and G represent efficient use of resources but in different economic conditions. Point F is preferred during economic booms, while G is achievable during recessions.
