Concept:Sovereignty means the supreme authority of a state over its own affairs, but it can be restricted by external rules that the state accepts.
Explanation:Sovereignty gives a state full control within its territory.
However, no state exists in complete isolation.
International laws and conventions are treaties and agreements made between states.
These cover areas such as human rights, environmental protection, and trade.
When a state signs and ratifies such agreements, it voluntarily accepts certain obligations.
These obligations can limit how the state acts both inside and outside its borders.
For instance, a state may have to change its domestic laws to match international human rights standards.
This can greatly reduce its freedom to act independently.
The other options, like the rule of law or separation of powers, are internal arrangements.
They do not limit a state's sovereignty as greatly as external international commitments do.
