The correct response regarding a consequence of Britain’s policy of appeasement is:
Stalin and Hitler signed the German-Soviet Nonaggression Pact.
While the other options are inaccurate in the context of appeasement, the signing of the Nonaggression Pact between Germany and the Soviet Union in 1939 can be viewed as a result of the weakened position of countries opposing Hitler, particularly influenced by British and French policies of appeasement towards fascist aggression in Europe.
