What does the term "Aryan" represent in Nazi ideology?

In Nazi ideology, the term "Aryan" specifically refers to a racial concept that values individuals of northern European descent, particularly those with traits such as light skin, blonde hair, and blue eyes. This classification was used by the Nazis to promote the idea of racial superiority, positioning Aryans as the so-called "master race." This notion underpinned many of their policies, including the exclusion and persecution of Jews and other groups deemed "racially inferior."

The ideology surrounding Aryan identity played a key role in justifying the Nazis' aim to achieve a homogeneous society based on these racial ideals. By establishing a hierarchy that placed Aryans at the top, the regime sought to legitimize its expansionist and exclusionary practices.

The other answer choices do not accurately reflect the core meaning of the term in this context. For instance, it does not encompass all German citizens regardless of descent, nor does it pertain to a religious identity. Additionally, describing it as a socio-economic class contradicts the racial emphasis central to Nazi beliefs.
