The correct answer is C.

Publishing a newspaper editorial that criticizes the country’s leaders would be strictly prohibited in Nazi Germany because of the censorship.

Censorship ensured that Germans could only see and hear what the Nazis wanted them to read to and to see, in other words, people were brainwashed into obeying the Nazis and idolizing Hitler.

All media were under such control and scrutiny that only the ideas and values of the Nazis were heard and seen by the masses. All aspects of media, culture and the arts were censored and used for the Nazi propaganda.  

The Minister of Propaganda, Joseph Goebbels, made sure that newspapers could only print stories favorable to and approved by the Nazis. Any kind of anti-Nazi critic was dealt with immediately and the author killed or put into a concentration camp.
