after it came to power, the communist party ruled russia as a\ndemocracy.\nmonarchy.\nrepublic.\ndictatorship.

Brief Explanations:

The Communist - led Soviet Union was a socialist state that adhered to the principles of the dictatorship of the proletariat. It was not a democracy in the Western - style sense, nor a monarchy or a republic in the traditional bourgeois sense. The dictatorship of the proletariat means that the working class and the broad masses of the people are the masters of the country, and the state power is used to safeguard the interests of the working people and promote socialist construction.

Answer:

None of the above options accurately describe the nature of the Soviet state. The Soviet Union was a socialist state based on the dictatorship of the proletariat. If we must choose from the given options, the closest in a very simplistic and inaccurate way of categorization might be misinterpreted as "dictatorship" (but this is a misnomer as it was the dictatorship of the proletariat, not in the negative connotation of a single - person or small - group autocratic dictatorship), but this is a very wrong - headed way of looking at it. A more accurate description is that it was a socialist state with power in the hands of the working people.
