The annexation of Austria made Germany the dominant power in central Europe, and it gave germany a border with Italy. So for the given question, the correct option is option "A". Austria was the birth place of Adolf Hitler. Although it can be said that the many austrians did not feel any difference when germany annexed Austria because the people of both the coutries shared the same language and crossing over to each others country became far more easy. As far as religion was concerned, people of both coutries were mostly catholic. This annexation did give hitler a big shot in the arm.
