Answer:
The answer is D. The period of isolationism.
Explanation:
US Commodore Matthew C. Perry´s mission was to make Japan open to trade. He first arrived in 1853, conveying a letter from the president of the United States. He returned in 1854. Perry´s mission effectively forced the end of the self-imposed isolation of Japan which had existed since the first half of the 17th century. Japan was closed to the outside world by the Tokugawa shogunate, only Dutch vessels were permitted to anchor at Yokohama´s bay and conduct limited trade with the Japanese.
