What statement best describes the relationship between world war 1 and the Russian revolution?

World War I significantly contributed to the Russian Revolution by exacerbating existing social, economic, and political tensions within Russia. The war led to military defeats, high casualties, and widespread discontent among the populace, undermining the Tsarist regime. This turmoil created an environment ripe for the Bolsheviks to gain support by promising peace, land, and bread, ultimately leading to the overthrow of the provisional government in 1917. Thus, the war acted as a catalyst for revolutionary change in Russia.
