Final answer:
Japanese leaders responded to Commodore Perry's 1853 visit by signing the Treaty of Kanagawa, opening ports to American ships and initiating friendly relations between Japan and the United States, setting the stage for the country's modernization. The correct option is B.
Step-by-step explanation:
Following the visit of Commodore Perry in 1853, Japanese leaders took action to open the country to international trade and diplomacy. Under the threat of American naval power and seeing the necessity of industrialization, the Japanese government was compelled to sign the Treaty of Peace and Amity after Perry's display of military force.
Consequently, the Treaty of Kanagawa was signed on March 31, 1854, leading to the opening of Japanese ports to American ships, thus marking an end to centuries of Japanese isolation.
The ports of Shimoda and Hakodate were opened to American vessels, which allowed for the provision of aid to shipwrecked American sailors, and promised friendly and peaceful relations between the United States and Japan. This event paved the way for the Meiji Restoration and Japan's rapid westernization and industrialization.
