Final answer:
Sovereignty is the right to rule oneself and have supreme authority within a nation. It involves self-governance, the ability to enter into treaties, and the structure of government.
Step-by-step explanation:
Sovereignty refers to the right to rule oneself. It is the supreme authority and power that a nation or state possesses within its own borders. It enables a country to make decisions and govern itself independently without interference from external forces or influences.
For example, in the context of international relations, when a country exercises its sovereignty, it has the ability to enter into treaties and agreements with other nations, like approving treaties mentioned in option C. Additionally, sovereignty extends to the structure of government (option D), as it determines how power and authority are distributed within a country.
In summary, sovereignty is about a nation's self-rule, the power to govern itself, the ability to enter into agreements, and the structure of its government.
