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.
Under the Articles of Confederation, the nation was governed by a legislature.
So the correct answer is A.
