Answer: A. On the curve.
Explanation:
Production possibilities curve (PPC) is simply a graphical representation that is used to show different combinations of two goods which a particular economy can produce when the economy uses the resources it has efficiently. 
Points on the curve shows that the resources in an economy are efficiently used, points on the interior of the curve shows that the resources are used inefficiently while the points that are beyond the curve shows are referred to as unattainable.
Therefore, if you are using your factors of production at 100% efficiency, you will be on the curve.

This provides a great benefit to any manufacturing company, hence why General Motors was interested.
