Answer: C. The new Bolshevik government quickly pulled Russia out of the war.
Explanation:
In October 1917 the socialist Bolshevik Party Led by Vladimir Ulyanov took control of Russia, promising peace, bread, and land. AS soon as they got to power, the Bolsheviks began peace negotiations with Germany. By March 1918, they had signed the Treaty of Brest-Litovsk, bringing Russia’s involvement in the war to its formal ending.
It would be "France" that was not an eastern european nation under communist control, since France was very much allied with Great Britain and the United States during the Cold War.
