Answer: (C). A step back from a free enterprise
Step-by-step explanation:
After the Cold war ended and the Communist Soviet Union was dissolved, Russia under Boris Yeltsin tried to become a market economy that championed principles such as free enterprise.
The change was too sudden and caused economic problems in Russia thereby making Yeltsin quite unpopular. He handed power to Vladimir Putin who nationalised the energy industry which was a step back from the free enterprise principle that had been championed by Yeltsin.
