Answer: A. Calls for independence from Eastern bloc nations
Explanation:
Mikhail Gorbachev was the last premier of the Soviet Union and he started a series of reforms which according to him, were meant to save the Soviet Union. He allowed for freedom of speech and multiple political parties.
The Eastern bloc nations of the Warsaw Pact interpreted this to mean that there was less chances of the Soviet Union interfering in their affairs and so demanded independence along with the Soviets that comprised the USSR. This led to the collapse of the Soviet Union.
