The correct option is D Renaming the Bolshevik Party as the Russian Socialist Party.
In November 1917, Lenin nationalised most of the industries and banks in Russia. The government now had control over the ownership and management of private assets. The next thing was declaration of land as a social property - that is, land was declared as the property of the masses. In the cities, large houses were partitioned according to the size of the family. If a family of three was living in a large bungalow, it was partitioned and given to those who needed it. The Bolshevik Party was renamed as the Russian Communist Party.
