The correct answer is A. The map illustrates the countries occupied by Germany during World War II.
In addition to the German territory during the Weimar Republic, the new Reich came to include, in the years preceding the Second World War, areas with Germanic ethnic populations such as Saarland, Austria (after the Anschluss is renamed Ostmark), Sudetes (Crisis of the Sudeten) and the territory of Memel. Regions acquired after the outbreak of World War II include Eupen and Malmédy (taken from Belgium), Alsace-Lorraine (taken from France), Danzig and various territories in central and northern Poland. In addition, from 1939 to 1945, the Third Reich annexed the Czech territory of the Czechoslovak Republic giving it the name of Protectorate of Bohemia and Moravia as a subjugated territory. Although this protectorate was considered a part of the "Greater Germany", it maintained its own currency and a commercial "internal border" with Germany.

Czech Silesia was incorporated in the province of Silesia in the same period. In 1942, the occupied Luxembourg was directly annexed as a province of Germany. The south and central regions of Poland were in charge of an occupation government called the General Government, although in a much less autonomous position than the Protectorate of Bohemia and Moravia, and with the persistent threat of totally "Germanizing" the territory and expelling the cities to the Polish population, with a view to total annexation in the future. At the end of 1943, after the surrender of the Kingdom of Italy, Germany was occupying Istria militarily and South Tyrol, which had been Austrian territory before 1918; although in this case there was no direct annexation, the Third Reich did not allow any control of this territory to the Italian Social Republic, and in fact these regions remained under German civil administration.
