Answer:
The correct option here is c) the net export will rise and the aggregate quantity of goods and services demanded would also increase.
Explanation:
When the value of dollar currency depreciates, the net export of US would rise because due to depreciation of the currency , the goods that are produced in US have now become cheaper and because of this the total aggregate demand of the goods and services produced in US has increased and thus all of this would lead to increase in export and decrease in import.
