Answer:
Option C (an aggregate demand shock) is the right solution.
Step-by-step explanation:
- Examples of such an overall demand shock are the same as the aforementioned, i.e. a rise throughout customer sales over the holiday season, a reduction in overseas imports of U.S. goods, a consumption tax, as well as a drop in new housing starts when they trigger a change in the AD curve.
- A transition exists in aggregate demand at that same specified price level.
And therefore option C seems to be the right alternative,
