The correct answer is C) The dismantling of the Berlin Wall and the end of restrictions on emigrating from communist countries.
A significant long-term cause of the collapse of the Soviet Union during the late twentieth century was the dismantling of the Berlin Wall and the end of restrictions on emigrating from communist countries.
After many years under the Communist regime, the Soviet Union split in December 1991. During those Communist years, the USSR never allowed private property in the Soviet United. The state was the owner of the means of production.
So when Gorbachev decided to implement glasnost and perestroika reformations, he had to carefully proceed because these involved some kind of risk. Glasnost allowed people more rights such as the freedom of speech and freedom of the press. Perestroika allowed new and private investments to revitalize the difficult economic conditions of Russia.
The Soviet Union ceased to exist on December 26, 1991. Gorbachev had resigned one day before and the new leader of Russia was Boris Yeltsin.

Your question is rather vague by just giving dates ... but I think I know what you might be looking for here. During the "antebellum" (before the Civil War) years and again in the years after the Civil War, there were strong movements by social activists that went against how society wanted to keep women and African Americans in "their place." Social reformers thought that the place assigned to women or to blacks was not at all right. They put forward better ideas of how black Americans and female citizens should have equal status with whites and with men in regard to political, social, and economic rights.
The activist movements from 1820 to 1848 and again from 1865 to 1898 didn't achieve all their goals in that time period, but they began to advance the causes of civil rights for blacks and women -- both movements which would continue into the 20th century.
