Answer:
A) Gorbachev hoped that the reform he brought to the Soviet Union would end the Cold War.
Explanation:
The Soviet Union's strict policies over its satellite countries and its citizens at home were ultimately making the once powerful world force weaker and were preventing diplomatic relations with many other countries.
With Gorbachev's introduction of the Glasnost policies, the United States and other countries were more willing to work with and have relations with the Soviet Union, something that had been cut under the strict censorship policies.
