Answer:
The correct answer is letter "A": knowing the history of exchange rate behavior.
Step-by-step explanation:
Forecasting exchange rates can help minimize risks and maximize returns. Forecasting techniques include technical forecasting, fundamental forecasting, and a mixture of the two of them. Technical forecasting uses historical exchange rate data to "predict" future exchange rates. Fundamental forecasting uses fundamental relationships among economic variables -interest rates, inflation, income, for instance- and exchange rates.
