The correct option is D Disintegration of Soviet Union
In December
of 1991, as the world watched in amazement, the Soviet Union disintegrated into
fifteen separate countries. Its collapse was hailed by the west as a victory
for freedom, a triumph of democracy over totalitarianism, and evidence of the
superiority of capitalism over socialism. The United States rejoiced as its
formidable enemy was brought to its knees, thereby ending the Cold War which
had hovered over these two superpowers since the end of World War II. Indeed,
the breakup of the Soviet Union transformed the entire world political
situation, leading to a complete reformulation of political, economic and
military alliances all over the globe.
