Answer:
The correct answer is option C.
Step-by-step explanation:
Suppose there is pessimism in an economy because of corporate scandals, international tensions, loss of confidence, etc. This is going to adversely affect the economy. Because of corporate scandals, the investment will decline. Loss of confidence in consumers will cause a reduction in consumption spending. International tensions cause net exports to decline.
All of this causes aggregate demand to decline. The aggregate demand curve moves to the left. This leftward shift causes both the quantity of output and price to fall. As output fall real GDP will decline as well.
