Answer: B. Opposition to absolute monarchy
Explanation: Revolutions that took place in Russia in 1917 were the result of absolute lack of awareness of Emperor Nicholas to solve the accumulated economic problems and problems of workers and peasants who were in a very difficult position. Although allegedly there were some concessions, such as the formation of the Duma, in practice, the absolutist mode of government did not change. The emperor was more engaged in warfare with Japan, which had devastated Russia and people. Even after the abduction of Tsar Nicholas, the fundamental changes came only after the Revolution and regime change.
