Answer:
C) producing more automobiles in the United States.
Step-by-step explanation:
All companies that engage in foreign trade suffer from currency exchange risks, because they cannot control the price of foreign currencies. An American company cannot control the price of the US dollar, how can it expect to control the price of the Japanese yen.
The solution will always be to increase manufacturing in the country, Honda realized that about 40 years ago when they started producing the Accord and then Toyota followed. This doesn't eliminate all the risks, since many parts are still imported from other countries, but at least they are reduced.
Once Honda's market share reached a certain amount of cars, they decided to built them in the US. Back then Japanese economy was booming, but their currency was also appreciating fast. The same happened to BMW and Mercedes Benz a few years later when the euro started appreciating.
