Its not much but, C IS NOT THE ANSWER. So cancel c from choosing, srry i couldnt be as of much help:(
I guess there are many answers to this depending on what your teacher is passing to you! But I believe the best answer to the posed question would be that Nazi propaganda's main purposed was to intimidate, threaten and empower themselves. I believe that this age was a huge problem due to the intimidation that Nazi Germany posed to other countries.
Hope I was able to help! If you have any further questions, please let me know!
