Governments are classified in all of the following ways except

a) the square miles of territory governed by its leaders
b) the number of people who work for the government
c) the relationship between making laws and enforcing them
d) the way that power is divided geographically

I believe the answer is: A) the square miles of territory governed by its leaders

The square miles of the territory is what we often refer to as 'States', not the government per se. The government focus on the organizational structure that are important in managing both economic and social regulations in a certain area.
