Answer:B, a dynasty created after Ieyasu defeated rival warlords and united Japan under one rule that closed Japan's borders to foreign trade in order to limit western influence

Ieyasu united the country and brought the nation under one ruler and noticing that the Europeans were spreading their influence on Asia and wanting to protect the nation's traditional values, he shut japan off off from the outside world for 200 years.
