Which one of the following best defines the term 'State'?
Explanation
Option (a) is correct because it encompasses the four essential elements of a State as defined in political science: population, territory, government, and sovereignty (independence from external control). Option (b) is the most tempting wrong choice as it describes the functions of a modern state, but it is technically incomplete because it fails to explicitly mention sovereignty, which is the defining legal characteristic of a State. This question tests the core concept of the "Four Elements of the State" required for international and legal recognition.
