Answer: Point C
Explanation:
When government purchases increases, there will be more money in the economy which will have a multiplier effect in the economy of increasing investment and consumption spending both of which will lead to new companies being founded and old companies increasing capacity.
The unemployment rate will therefore decrease as more people are hired to boost capacity but the inflation rate will increase because of the rise in demand. The only point on the graph that shows these two things in point c so that is where the economy will move to in the short run.
