Nazi messages like one nation, one leader were linked with which political principle?

Führer principle and centralised authoritarianism

The slogan “one nation, one leader” expressed the Führer principle, according to which authority was concentrated in Hitler and obedience to him was treated as the basis of political unity. It rejected pluralism, independent institutions, competing parties, and the idea that leaders should be limited by open criticism or constitutional checks. The state, the party, and society were expected to follow a central command rather than negotiate among diverse interests. Option A is therefore correct because the slogan legitimised centralised authoritarian rule and leader worship. Option B would require competing parties and public choice, which Nazism suppressed. Option C suggests dispersed power, the opposite of centralisation, while D refers to an international socialist idea that Nazism explicitly opposed.
