When establishing an ad campaign in a foreign country, what does the difference in currency exchange rate affect the most?

A) the cost structure of the ad campaign

B) the creative strategy of the ad

C) media used for the advertisement

D) the company's brand name

Option A. The cost structure of the ad campaign

The reason is that the currency exchange rate effects the transactions of money from home to foreign or foreign country to home country. So the option with money transaction is option A.

The rest of the options are planning and are things that are not associated with the foreign transactions. So the remainder options are not the one which will be effected by the currency exchange rate.
