The correct answer is option 1, R. Hess. R. Hess was a prominent figure in Nazi Germany and held several high-ranking positions in the Nazi Party. He was known for his loyalty to Adolf Hitler and played a crucial role in the establishment of the Nazi regime. The quote mentioned in the question reflects his ideology and belief in the inseparable connection between Hitler and Germany. Hess emphasized that pledging allegiance to Hitler meant pledging allegiance to Germany itself. It is important to note that while Mussolini was an ally of Hitler and leader of Fascist Italy, he did not make this particular statement. Similarly, option 3, Hitler, is incorrect because the quote is attributed to someone else. Option 4, Communist International, is unrelated to the quote and can be disregarded.
