Answer: C. Region B
Explanation:
Region B is the North American continent which includes the United States. Land here is quite fertile and resources are plentiful as the continent boasts of vast farmlands, timber and an abundance of coal.
The people of this continent therefore need not import a lot of things. They do however have to import oil. Even though there are rich oil deposits present, these are sometimes quite expensive to extract which is why the region needs to import some of the oil that its people need.
