After the assassination of whom did the war trigger immediately
-
Chancellor Bismarck
-
Archduke Franz Ferdinand
-
Wilhelm II
-
Gavrilo Princip
B
Correct answer
Explanation
Archduke Franz Ferdinand's assassination on June 28, 1914, in Sarajevo was the immediate trigger for World War I. His death set off a chain reaction of alliances and declarations of war. Gavrilo Princip was the assassin who killed him, not the person whose death triggered the war. Chancellor Bismarck was a 19th-century German leader, and Wilhelm II was the German Kaiser during WWI but was not assassinated.
