A sovereign state is one

A sovereign state is an independent political entity that has supreme authority over its own affairs within its territorial boundaries. This means that the state is free to govern itself without interference from other countries or external forces. The state's government is responsible for making decisions regarding its own internal and external affairs, and its citizens are expected to follow its laws and policies. Sovereignty is not invested in the military, but in the government, which is responsible for protecting the state and its citizens. A sovereign state's constitution may be changed by its own government or by its citizens through a democratic process, and citizens are expected to take responsibility for their actions. Therefore, is the correct answer.
