Final answer:
The correct answer is C) A universal truth, as all countries have some form of government that exercises control over its people. Governments vary in structure and are influenced by political ideologies and historical developments in concepts like liberty and self-governance.
Step-by-step explanation:
The statement "All countries in the world have some sort of government system" aligns best with option C) A universal truth. Throughout history and geography, varying forms of government, from monarchies to democracies, have been established to exercise control and provide organization within a society. Governments ensure the implementation of laws, policies, and social benefits and may differ in structure, from unitary systems to federal and confederal systems.
Political ideologies profoundly influence these government structures, with concepts such as the social contract theory and political legitimacy underpinning the authority of different ruling systems. The evolution from monarchies to more egalitarian systems signifies ongoing changes in governance, shaped by the ideologies of liberty and self-governance initiated by thinkers like John Locke and realized through historical developments in places like North America and France.
