Answer:
The correct answer is B. Mikhail Gorbachev differed from previous Soviet leaders as he recognized that the Soviet Union needed to adapt.
Step-by-step explanation:
When Mikhail Gorbachev came to power, he found a country with serious problems. After the death of Stalin three decades earlier, the denunciation of his repressive methods never led people to question the communist monopoly of power. On the other hand, the arms race with the West had contributed to economic stagnation.
To change things, Gorbachev announced a program of reforms that would become popular through the slogans of perestroika (restructuring) and glasnost (transparency). Its objective was not to establish a democracy, but to proceed to a revitalization of socialism. But what it achieved was just the opposite: the fall of the communist system and the dissolution of the Soviet Union.
