Answer:
B. value of the country's exports minus the value of its imports
Step-by-step explanation:
That is the definition of net exports in economics: the value of a nation's total exported goods and services minus the value of all imported goods and services (NX = EX - IM)
Net exports could be positive or negative, depending on whether exports are larger or smaller than imports
It is seen frequently in talking about GDP, with the national income of an open economy being the sum of Governemnt Spending, Consumption, Investment and Net Export (Y = G + C + I + EX - IM)
