Answer:
c. Serbs wanted the Slavic areas of Austria-Hungary to separate from the empire and become a part of Serbia.
Explanation:
Serbian nationalists promoted the liberation from Austria -Hungary and wanted to unify Serbs present in the different Balkan nations.
Although they did not want to confront the large multinational Empire of Austria, they sought independent states. A wave of so-called pan Slavism was promoting unity between all Slavic peoples.
Serbia was one of the most active in nationalist and political radical parties encouraged the feelings of a unified Serbia.
Serbia was an independent nation supporting its neighbouring Slavic partners to embrace nationalism as a state nation.
Serbia had strong support from the largest empire -The Russian Empire.
<em> These nationalistic tendencies would spark to bring about World War I in the Balkans, an often contested and already unstable region. </em>
