Which modern countries were part of the Austro-Hungarian Empire?

The Austro-Hungarian Empire, which existed from 1867 to 1918, encompassed a diverse range of nationalities and territories in Central and Eastern Europe. The modern countries that were part of this empire include Austria, Hungary, and the Czech Republic, which was part of the Kingdom of Bohemia within the empire. These regions played significant roles in the political, cultural, and economic life of Austro-Hungary.

The empire was known for its complex administrative structure, which reflected the multi-ethnic nature of its inhabitants. The choices that involve Germany, France, and Italy, Iran, Iraq, and Turkey, as well as Russia, Poland, and Ukraine, do not accurately represent the territories that comprised the Austro-Hungarian Empire. Each of these groups relates to different historical entities and geopolitical developments that are distinct from the Austro-Hungarian context. Thus, the selection of Austria, Hungary, and the Czech Republic aligns correctly with the historical parameters of the Austro-Hungarian Empire.
