Option A. Countries involved in the international trade must know the value of each other's money. The need for an International Currency System is because international transactions with different currencies are linked to an economic reality of each country with different measures and prices or exchange rates of each country. The different types of currencies depend on the supply and demand of each currency, regulated by national central banks that control the fluctuations of each currency. This system works like the exchange of currencies of one currency for another for the acquisition of different currencies and commercial transactions.
