The correct option is B
The Russian Civil War was a multiple armed conflict that took place between 1917 and 1923 in the territory of the dissolved Russian Empire, between the new Bolshevik government and its Red Army, in power since the October Revolution of 1917, and on the other side the military of the former tsarist army, grouped in the so-called White Movement, composed of conservatives and liberals, favorable to the monarchy and closely related to the Russian Orthodox Church, as well as democratic socialists: revolutionary socialists and Mensheviks opposed to the Bolshevik revolution.
Lennin was the main Bolshevik leader of the October Revolution of 1917. Already in power, Lenin proceeded to implement various reforms that included the transfer to the State or the Soviet workers of control of property and land in the hands of the aristocracy, the ancient crown or landlords. Faced with the threat of an invasion by the German Empire, he signed a peace treaty that led to the departure of Russia from the First World War. In 1921, Lenin's government established the New Economic Policy, which combined socialist and capitalist elements and initiated the process of industrialization and recovery of the country after the Russian civil war, a tough conflict that included the participation of fourteen foreign nations against the new Soviet state.
