Answer:
c. The U.S has a trade deficit. The U.S. purchases $800 billion worth of foreign assets and foreign countries purchase $600 billion worth of U.S. assets.
Explanation:
Exports = Â $300 billion
Imports = Â $500 billion
Trade surplus/(deficit) = Â $300 billion - $500 billion
                  = ($200 billion)
Considering all the options,
Purchases = $800 billion
Sales = $600 billion
Trade surplus/(deficit) = $600 billion - $800 billion
                  =  ($200 billion)
Hence the right answer is c. The U.S has a trade deficit. The U.S. purchases $800 billion worth of foreign assets and foreign countries purchase $600 billion worth of U.S. assets.
