Answer:
B. In the long run, a change in the nominal exchange rate brings an equivalent change in the real exchange rate.
Step-by-step explanation:
As we know that in the short run there is a decline in the nominal exchange that results in a decrease of real exchange rate due to which there is a reduction of the import and the export is risen.
But in the case of the long run, if there is a change in the nominal exchange rate so the real exchange rate would remain the same
This results that if there is a change in the nominal exchange rate so it would not bring the equal change in the real exchange rate
Hence, option B is incorrect
