I'll be glad to check your answer.

To determine the correct answer, we need to understand the events leading up to British Prime Minister Chamberlain's declaration of a final act of appeasement.

In 1938, Adolf Hitler's Germany was expanding its territories and asserting its dominance in Europe. The first significant event to consider is the annexation of Austria, known as the Anschluss, which took place in March 1938. This event is not directly related to Chamberlain's declaration.

However, the next crucial event was Hitler's claim on the Sudetenland, a region in Czechoslovakia with a significant German-speaking population. Hitler demanded that the Sudetenland be given to Germany. This led to the Munich Agreement in September 1938, where British Prime Minister Chamberlain, along with French Prime Minister Daladier, agreed to Hitler's demands to avoid war. This is referred to as the policy of appeasement.

Therefore, the correct answer is B. Chamberlain declared a final act of appeasement when Hitler's claim on the Sudetenland was accepted.
