Under the Indian Constitution, concentration of wealth violates

1. The question asks which part or principle of the Indian Constitution is violated by the concentration of wealth. 2. Article 39(c) of the Constitution, which is part of the Directive Principles of State Policy (DPSP), explicitly directs the State to ensure "that the operation of the economic system does not result in the concentration of wealth and means of production to the common detriment." 3. Therefore, the concentration of wealth directly violates the letter and spirit of the Directive Principles of State Policy. 4. While extreme concentration of wealth might have implications for the Right to Equality (A) or the broader Concept of Welfare (D), the most direct and explicit constitutional violation is related to the DPSP, specifically Article 39(c). 5. The Right to Freedom (C) deals with different sets of liberties. Hence, the Directive Principles of State Policy is the correct answer.
