What kind of reform had Gorbachev done within USSR?

The correct answer is Option 2 - Economic and Political Reforms.

Gorbachev initiated the policies of economic and political reform and democratisation within the country. The reforms were opposed by leaders within the Communist Party. A coup took place in 1991 that was encouraged by Communist Party hardliners. The people had tasted freedom by then and did not want the old-style rule of the Communist Party. Boris Yeltsin emerged as a national hero in opposing this coup. The Russian Republic, where Yeltsin won a popular election, began to shake off centralised control.
