Draw a production possibility curve and show the efficient and inefficient combinations of production of an economy on the curve?

The Production Possibility Curve (PPC) illustrates the maximum combinations of two goods (e.g., wheat and cloth) an economy can produce with given resources and technology. Points A, B, and C on the curve represent efficient production—full utilization of resources. Points D and E lie inside the curve, indicating inefficient production (underutilization of resources). Point F lies outside the curve, representing an unattainable combination with current resources. The downward slope reflects the opportunity cost of producing more of one good at the expense of another.
