B. Warsaw Pact

Explanation:

The Warsaw Pact is a Treaty signed by the Soviet Union and its European satellites, on May 14, 1955, in the Polish capital. It originates from the Conference of the eight communist governments in Warsaw, from May 11 to 13, 1955.  It was composed of Albania, Bulgaria, Czechoslovakia, Hungary, Poland, Romania, East Germany and the Soviet Union, with a single Command that had its Headquarters in Moscow, advised by a Council of Ministers, an Advisory Committee, a Combined General Staff and the Supreme Command of the Unified Armed Forces (considered the most important organ of the system) competent for strictly military affairs.

Its mission was the mutual defense against any attack on one of the members and the consultation on international affairs that would affect the security and defense of the group of nations that formed it.  The pact was motivated by the formation of the Western European Union, with the participation of West Germany and its integration into the North Atlantic block.
