Answer: Export manufacturing.
Step-by-step explanation:
As you included no options, I can only give a general answer.
The scenario described above is export manufacturing. Export manufacturing is a strategy where a company produces goods solely for the purpose of exporting them to another country for sale.
This is what is happening in the scenario above. The U.S. based company is producing goods in the United States then sending them to Canada to be sold thereby engaging in export manufacturing.
