c. People enjoyed economic freedom

The people in the soviet economy did not enjoy economic freedom. Every economic policy was framed by the state. There was no institution of private property and the society was based upon principles of economic equality.

Option A is correct because the Soviet economy was based upon the idea of communism and socialism intending to provide equal stature and benefits to all its citizens under a social and economic structure all of whose aspects were governed and managed by the state.

Option B is correct as the state exercised its control over every economic activity. Right from production to the sale of goods, everything was controlled and owned by the state. All the land, labour and capital were owned by the state.

Option D is correct because the Soviet propagated the ideology of communism under which every aspect of economy was owned by the state and distributed among its citizens equally.
