The assassination of Archduke Franz Ferdinand triggered a series of events that led to the collapse of the alliance system in Europe, as countries were obligated to support their alliance partners.

C. The nationality of Archduke Franz Ferdinand's assassin: The nationality of the assassin, Gavrilo Princip, was Serbian. While this is crucial information to understand the immediate circumstances surrounding the assassination, it alone cannot fully explain why it sparked World War 1.
