It united Europe against the Ottoman Empire is not an accurate description of the role nationalism played in causing World War I.
WWI
World War I began after the assassination of Arch du ke Franz Ferdinand.
The role of nationalism played a significant role in WWI as the ruling dynasties began to fall as they lost their control over their nations.
The war was fought as the rivalries between European nations began because of imperialism and militarism.
Therefore we can conclude that the war has nothing to do with going against the Ottoman Empire.
Thus option C is the correct answer.
