Correct Option (D)
Neither 1 nor 2.
The Directive Principles of State Policy (DPSPs), enumerated in Part IV of the Constitution (Articles 36-51), are non-justiciable. This implies they are not legally enforceable by any court and therefore do not impose direct limitations on the legislative or executive functions of the state. Instead, DPSPs are fundamental in the governance of the country and serve as guiding principles for the state in making laws and formulating policies. They aim to establish a welfare state by promoting social and economic democracy.
Incorrect Options:
Options (A), (B), and (C) are incorrect because DPSPs do not function as limitations on either legislative or executive power. Their role is advisory and aspirational, guiding the state towards achieving certain socio-economic objectives rather than restricting its operational scope. While courts may refer to DPSPs for interpreting constitutional provisions, particularly in conjunction with Fundamental Rights, they do not act as direct constraints on governmental functions in the manner that Fundamental Rights or other constitutional provisions might.
