How do international norms independently impact the advancement of human rights?

Norms influence States through internalisation, legitimacy and social pressure, none of which is captured by the listed claims: "They do not, because states are only influenced by the pursuit of power." ignores the effect of norms, "Governments feel guilty if they do not try to protect and advance human rights." reduces it to guilt, and "The UN is able to enforce international human rights norms." overstates UN enforcement powers. Hence "None of the given options is correct"
