Answer:  C. The role of Serbian and Slavic nationalists in the assassination of the Austrian Archduke.

The ultimatum came after Franz Ferdinand, the archduke of Austria, was assassinated along with his wife in Serbia.  On July 23, 1914 (about a month after the assassination), the government of Austria-Hungary issued an ultimatum to Serbia.  Briefly, the ultimatum demanded that Serbia would ...

  • allow Austria-Hungary to conduct an investigation into the assassination;
  • stop all anti-Austrian propaganda being circulated in Serbia;
  • eliminate all terrorist groups such as the Black Hand, which was the group believed to be responsible for the archduke's assassination.

The government of Austria-Hungary demanded an answer from Serbia's government within 48 hours, or war would happen.  And war did happen -- a conflict that ended up involving many other countries, which we now call World War I.
