What nazi ideology led to the mass murder of jews known as the holocaust?

B) The belief that white non-Jewish "Aryans" were a superior race.

Hitler believed that there is a superior race, the "Aryans", which consisted of white people and Germans. Non-Aryan's included, for example, but not limited to, Russians, Jews, LGBT's, etc. Those who Hitler deemed 'Non-Aryans' were sent to labor or death camps, which, afterwards will soon be known as the Holocaust.

hope this helps

no every country is held to the same degree as others just some member countries such as the usa and germany are more economically sound so the need to show there support to all others
