The correct answer would be option C, Exchange Rate.
When planning a trip to Spain, Brett and his wife, both Americans, were concerned about how much they could afford to spend in Europe because sometimes the U.S. dollar will buy more goods and sometimes it will buy less, based on changing economic conditions. The Exchange rate is the rate at which the currency of one area or country can be exchanged for the currency of another’s.
Explanation:
When one currency of a country is exchanged with the currency of another country, the rate at which the currencies are exchanged is called as the exchange rate.
For example while planning a trip to Europe from America, the couple have US dollars which they need to exchange in Euros to be able to use the currency in Europe.
Roughly, a Euro is equivalent to 1.08 US Dollars, as of today. So this 1.08 dollars will be the exchange rate for US dollars to Euro.
