Question

the crisis that spurred the un to create an international law against genocide was the armenian genocide holodomar holocaust cambodian genocide

Explanation:

After World War II and the Holocaust (the systematic, state - sponsored persecution and murder of approximately six million Jews by the Nazi regime and its collaborators), the international community was shocked. The atrocities of the Holocaust led to a global recognition of the need to prevent such genocidal acts in the future. The United Nations Convention on the Prevention and Punishment of the Crime of Genocide was adopted in 1948, largely in response to the Holocaust.
The Armenian genocide (1915 - 1916) happened before the establishment of the UN (1945). The Holodomor (1932 - 1933) was a man - made famine in Soviet Ukraine, but it did not directly lead to the UN's genocide convention. The Cambodian genocide (1975 - 1979) occurred after the UN's genocide convention was already in place.
