Answer:
The aggregate demand will fall.
Step-by-step explanation:
The appreciation of currency makes import cheaper and export costlier. For example, a stronger dollar can buy more commodities from a foreign nation. Conversely, the foreign nation won’t be able to buy more commodities from the U.S. thus, the export will fall in the U.S. and imports will increase. So, a fall in net export results in a fall in aggregate demand.
