Which is a system of leaders who carry out the work of government?

a. aristocracy
b. bureaucracy
c. democracy

I think the answer to this is C

c: makes the most sense, An aristocracy the highest class in certain societies, especially those holding hereditary titles or offices. Bureaucracy is a system of government in which most of the important decisions are made by state officials rather than by elected representatives and a democracy a system of government by the whole population or all the eligible members of a state, typically through elected representatives.
