D. The United States desired to open up trade with Japan, which previously had been mainly closed to trade with foreigners.
Step-by-step explanation:
Japan had previously been closed to trading with foreign countries and they did not plan to trade either. They did not have any forces to stop the demanding of trade, like the navy, so when Commodore Perry went to Japan to demand them to trade, they had no choice. Japan was essentially forced into trade with the United States.
