Which is an appropriate summation of the rise in nationalism that helped lead to World War 1?

The rise in nationalism before World War I was characterized by intense pride in national identity and a desire for self-determination among various ethnic groups. This fervor often fueled rivalries between nations, particularly in Europe, as countries sought to assert their dominance and protect their interests. Nationalistic sentiments contributed to the destabilization of multi-ethnic empires, such as Austria-Hungary and the Ottoman Empire, leading to increased tensions and alliances that ultimately culminated in the outbreak of war. The assassination of Archduke Franz Ferdinand in 1914 served as a catalyst, igniting these underlying nationalistic conflicts into a full-scale global conflict.
