unemployment in the united states and china
the history of international trade

Explanation:

The graph shows total merchandise exports of the United States and China from 2010 - 2012. The title should reflect this data focus. "Total Exports for the United States and China" is most appropriate as it specifically mentions the two countries and the type of data (exports). The other options are either too general (e.g., "The History of International Trade") or not related to the content of the graph (e.g., "Unemployment in the United States").

Answer:

Total Exports for the United States and China
