What is the basic independent unit of world politics a country B province, C nation D organization

The basic independent unit of world politics is a country or nation. A country is a geographic area that is recognized as an independent political entity, with its own government and sovereignty. It is typically defined by its territorial boundaries and population. Provinces, on the other hand, are subdivisions within a country or nation, often with some degree of regional autonomy or administrative power. Organizations, such as international bodies or institutions, are also important actors in world politics, but they do not have the same level of sovereignty or political authority as countries or nations.
