The correct answer is Letter D
The answer is: United States would have a deficit of $11 billion in the given year.
A trade surplus occurs when a country exports more than it imports. On the other hand, a deficit is when a country imports more products than it exports.
In the above example, the United States is exporting only $5 billion of goods but importing $16 billion of products. This means that the total trade deficit in the example is 16-5 = $11 billion.
This actually represents the current situation of the United States where it has a significant trade deficit with many major economies in the world, most noticeably with China.

17. Convection
Remember conduction is through objects, convection is air rising and falling, and radiation is heat traveling through space
