Question

what role does territory play in state formation?
its optional for statehood
it defines the states physical limits
it determines population size
it creates national identity

Explanation:

Territory is a fundamental element in state formation. It provides the physical space within which a state operates. It is not optional for statehood as per international law and political theory. National identity is more about the people's sense of belonging (not territory - specific). Population size is about the number of people (not territory). Territory clearly defines where a state's jurisdiction, resources, and people are located, i.e., its physical limits.

Answer:

It defines the state's physical limits.
