• A. Sakoku or "locked country" policy
• B. Tenka Fubu

• D. Ieyasu Doctrine

Answer: (A)

The correct answer is the Sakoku or "locked country" policy, which characterizes Japan's strategy during the Edo Period to limit foreign influence and interactions, particularly with Western nations. This policy was officially enforced under the Tokugawa shogunate starting in the 1630s. Its primary aim was to maintain social order and political stability by preventing foreign ideas, religion, and trade from permeating Japanese society.
