 A had to take an oath pledging their life to Hitler, the savior of Germany.

All members of the military and civil service were indeed required to take an oath of loyalty to Adolf Hitler. For the military, this was known as the Reichswehreid, and it was instituted after Hitler became Führer in 1934, following the death of President Hindenburg. The oath pledged unconditional obedience to Hitler personally, not to the office or the state, which was a significant departure from previous German military tradition.

The oath for soldiers of the Wehrmacht (military) was as follows: "I swear by God this sacred oath that I will render unconditional obedience to the Führer of the German Reich and people, Adolf Hitler, supreme commander of the armed forces, and that as a brave soldier I will be ready at any time to stake my life for this oath."

This oath was a powerful tool for ensuring the loyalty of the military and bureaucrats to Hitler. It effectively tied the state's functioning and the military's might to Hitler's personal leadership. The Hitler Youth was an organization for young people, primarily aged 10 to 18, with programs that were designed to indoctrinate the youth with the Nazi ideology, including anti-Semitism, and to prepare them for service to the state and party.

Although the Hitler Youth and other organizations also preached anti-Semitic ideology, item B ("were forced to adopt anti-Semitism") was not a formal requirement like the oath but was indeed part of the indoctrination. As for item C ("had to be at least 18"), this does not hold true for membership in groups like the Hitler Youth, where children under 18 were indoctrinated from an early age. So, while age limitations applied to military service, that was not a universal requirement for participation in all Nazi organizations.

Through these mechanisms of control and indoctrination, Hitler secured the loyalty and commitment of the population, especially the youth, to ensure that German society was aligned with, and actively supported, the goals and values of the Nazi regime.
