Answer:
d. governmental power became centralized under the shogun, while the emperor ruled in name only.
Step-by-step explanation:
The Shogunate system was established in Japan by Tokugawa Ieyasu in 1603 and lasted till 1867. Under this system, the Shoguns upheld all major executive powers while the emperor remained confined within the capital, Kyoto.
The Shoguns served as the landlords among the distributed regions in the country. Each regional administration had a Shogun who controlled the whole political, social and economical spheres of that particular region.
This system mobilized the powers of the emperor and controlled the whole administrative system. The emperor remained as the head of the country but ruled in name only.
