In the Austrian Empire, the groups which wanted to establish an autonomous state were B. Czechs and C. Hungarians.As you probably know, the entire name of the empire is Austro-Hungarian Empire, which means that included both of these countries (as well as what is now considered to be Czech Republic). So obviously those groups wanted to separate and create their own nations.
The correct answer is legislative.
The military falls under the jurisdiction of the legislative portion of the government because Congress (which is the legislative branch) has the ability to declare war. Since Congress has the ability to declare war, not having a military would greatly affect their ability to protect the US. This was one of several problems within the Articles of Confederation. The Articles of Confederation was America's first constitution and was eventually replaced after less than a decade by the US Constitution (still in use today).
And, what is your question?
