What are "political boundaries" in geographical terms?

Political boundaries refer to the imaginary lines that delineate the territorial limits of countries, states, regions, or municipalities. These boundaries are established through legal agreements or historical claims and serve to define the areas of governance and jurisdiction. They dictate the political landscape, including where laws apply and how resources are managed. Political boundaries can influence a range of factors such as trade, culture, identity, and conflict.

Natural barriers, geological features, and population centers describe different aspects of geography but do not specifically define political boundaries. Natural barriers may affect where these lines are drawn but are not the boundaries themselves. Geological features relate to the physical characteristics of the earth and do not encompass the political implications of boundary designations. Population centers are locations with a high concentration of inhabitants and can often exist across political boundaries, making them irrelevant to the definition of the boundaries themselves. Hence, the correct understanding of political boundaries lies in their role as delineations in governance and territorial definition, which aligns precisely with the chosen answer.
