Correct option is A
The correct answer is (a) Part IV.
Part IV, Art 36 to 51 of the Constitution of India incorporates the Directive Principles of State Policy.
These principles are guidelines for the framing of laws by the government.
They aim to create social and economic conditions under which citizens can lead a good life.
Unlike Fundamental Rights (Part III), Directive Principles are non-justiciable, meaning they are not enforceable by any court.
