Answer:
The correct answer is option E.
Explanation:
The Philips curve shows the inverse relationship between inflation and unemployment. The Philips curve, in the short run, is downward sloping L shaped indicating this inverse relationship.
But according to economists, in the long run, there is no trade-off between inflation rate and unemployment. The inflation and unemployment are related in the short run, they are not related in the long run.
The long-run Phillips curve is a vertical line at the point of the natural rate of unemployment.
