If a nation is defined as 'Community of Communities', which term can be suitably given to a body that successfully claims a monopoly of legitimate force in a particular territory?

State

The correct answer is Option (3) → State

At the simplest level, a nation is a sort of large-scale community – it is a community of communities. Members of a nation share the desire to be part of the same political collectivity. 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”
