Which one of the following statements best reflects the Chief purpose of the 'Constitution' of a country?

The core concept tested is **Constitutionalism**, which posits that the chief purpose of a constitution is to define and limit the powers of the government to prevent arbitrary rule and protect individual liberties. While option (b) is tempting because a constitution does provide the framework for creating political offices, this is merely a functional role; the fundamental *raison d'être* of a constitution in a democracy is to ensure a "limited government." Therefore, option (c) is the most accurate as it captures the essence of a constitution as a check on state authority.
