How did Hitler and Goebbels exert control over literature?

The answer C is correct because Hitler and Goebbels enforced strict control over literature as a means to uphold Nazi ideology and suppress dissent. They implemented a policy where all publications required official permission to be published, effectively limiting the range of viewpoints available to the public. This censorship allowed the regime to eliminate any literature that contradicted or challenged Nazi beliefs. Additionally, the iconic book burnings organized by the Nazis, which targeted works deemed "un-German," further demonstrated their commitment to controlling the cultural narrative. These actions were part of a broader strategy to manipulate public opinion and ensure that literature served the interests of the state, reinforcing Nazi ideology while marginalizing alternative perspectives.
