Which statement best summarizes the effect that World War One had on Russia?

The correct answer is B) The Russian government was weakened and eventually overthrown in a revolution.

During World War I, the Russian Empire was a vast empire based in an agricultural economy with a large poor population. The worker masses, led by Vladimir Lenin and the Communist party, organized in Soviets (councils) and following the Marxist precepts started a revolutionary movement that overthrown the Imperial government in October 1917 and established the first Communist government under the name of Union of Soviet Socialist Republics. As a result of this, Russia left the war.

Explanation:

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
