Florida Civics EOC Practice Test

The US State Department is responsible for handling international relations, which includes maintaining diplomatic relationships with other countries, negotiating international agreements, and representing the United States in international organizations. This is different from managing the country's defense (A), overseeing domestic policies (B), or controlling the national budget (D), which are the responsibilities of other branches of government. While these are important functions, they do not fall under the jurisdiction of the State Department. Therefore, option C is the most accurate and appropriate role for the US State Department.
