Answer:
The correct answer is A. As an immediate outcome of the fall of the Soviet Union, the Cold War ended.
Step-by-step explanation:
The fall of the Soviet Union was the disintegration of federal political structures and the central government of the Union of Soviet Socialist Republics (USSR), which culminated in the independence of the fifteen Republics of the Soviet Union between March 11, 1990 and December 25, 1991. The Treaty of Belavezha was an international agreement signed on December 8, 1991 by the presidents of Russia, Ukraine and Belarus (Boris Yeltsin, Leonid Kravchuk and Stanislav Shushkievich, respectively) in the nature reserve of Belovezhskaya Pushcha. The signing of the Treaty was communicated by telephone to the president of the Soviet Union Mikhail Gorbachev by Stanislav Shushkevich. These agreements declared the official dissolution of the USSR ending the validity of the Treaty of Creation of the USSR and the establishment of states in the former Republics of the Soviet Union. The dissolution of the world's largest socialist state marked the end of the Cold War.
