The correct answer is Option (3) - M. Weber.

This desire for political unity usually expresses itself as the aspiration to form a state. In its most general sense, the term state refers to an abstract entity consisting of a set of political-legal institutions claiming control over a particular geographical territory and the people living in it. In Max Weber’s well-known definition, a state is a “body that successfully claims a monopoly of legitimate force in a particular territory”
