A. The Fujiwara were pushed out of power and the government weakened.

The correct answer is A. The Fujiwara were pushed out of power and the government weakened.

During the Heian period in Japan, the Fujiwara clan held significant power and influence. However, over time, the Fujiwara clan became weakened due to internal power struggles. This weakening of the central government led to a power vacuum, creating an opportunity for local landowners and provincial warriors to gain power and establish their own fiefdoms. This gradual decentralization of power eventually gave rise to the feudal system in Japan, with local lords known as daimyo governing their own territories and pledging loyalty to the shogunate.
