The answer is  B. It caused both Great Britain and France to declare war on

Germany.

Explanation:

Before attacking Poland on September 1, 1939, Hitler had annexed Czechoslovakia on the grounds of his Lebensraum policy, or vital living space for the Germans. The  response of the Western powers was appeasement. They didn´t do anything in exchange for a promise of not making further demands. That was just a trick by Hitler. The following victim of the conquest push was Poland, which had just emerged as a contemporary state following WWI and the Treaty of Versailles. When Nazi Germany invaded Poland, France and Britain declared the war on Germany , but they did come to Poland´s help nor attacked. They did nothing until 1940, when Hitler´s armies attacked Belgium and France.
