b. it reformed the soviet government into a modern democracy.
c. it strengthened communist control of the soviet union.
d. it brought in economic reforms that saved the soviet economy.

Soviet leader Mikhail Gorbachev, in the period from 1985 to 1991, worked on reforming the Soviet Union and Communism, introducing Perestroika, which led to the collapse of the Soviet Union, the enormous weakening of the Communist Party, and the abolition of the Warsaw Pact. Following the abolition of the Soviet Union and the establishment of the Russian Federation, the governments of Russia went through the transit period of consolidation of the economy and redirection to market flows, sometimes less, sometimes more successful. It can not be said that the reformed economy has helped the government to develop into a modern democracy, nor that the old way of the Soviet economy was held and saved.

The answer is A.
