Answer:
True.
Explanation:
The statement is “True” because the Philip curve is the curve that exhibits the relationship between the inflation or price level and unemployment. If inflation rises, then unemployment falls. If inflation falls, then unemployment rises. This happens because there is a negative relationship between inflation and unemployment. However in the long run the Philip curve is a verticle line parallel to the inflation axis and that shows there is no trade-off. Thus the option A is correct.
