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

1. A Constitution serves multiple purposes, including laying down fundamental principles, establishing governmental structures, and outlining the rights and duties of citizens. 2. Option (A) is partially true, as a constitution sets objectives (often in the Preamble or Directive Principles) that guide law-making, but it's not its sole or chief purpose. 3. Option (B) is also true; a constitution enables the creation of political offices and the structure of government. However, this is a functional aspect rather than the ultimate purpose. 4. Option (D) lists important goals (social justice, social equality, social security) that a constitution may aim to secure, but these are aspirational goals achieved through the constitutional framework, not the definition of the framework itself. 5. Option (C) states that a constitution defines and limits the powers of government. This is considered the cornerstone of constitutionalism – establishing a system of limited government where power is not absolute and is subject to constraints, often to protect individual rights. This best reflects the chief purpose of a constitution in preventing arbitrary rule and ensuring governance according to established principles. 6. Therefore, defining and limiting governmental power is the most fundamental or chief purpose.
