The correct answer to this question is Option 4: Neither 1 nor 2.

The Directive Principles of State Policy (DPSP) in the Constitution of India are non-justiciable principles that guide the State in the governance of the country. They are not enforceable by any court of law but are fundamental in the governance of the country. The DPSPs are contained in Part IV of the Constitution, which is distinct from the Fundamental Rights in Part III.

The DPSPs are not limitations on the legislative or executive functions of the State, but rather guidelines for the government to ensure the welfare of the people. These principles are aimed at promoting social and economic democracy, reducing inequalities, and improving the standard of living of the people.

The legislative and executive functions of the State are limited by the fundamental rights enshrined in Part III of the Constitution. These rights are enforceable by courts of law, and any law or action that violates these rights can be struck down by the judiciary.

It is important to note that while the DPSPs are not enforceable, they are still considered fundamental to the governance of the country. The courts have recognized the importance of the DPSPs in interpreting laws and policies and have used them as a guiding principle in their judgments.

In conclusion, the Directive Principles of State Policy are not limitations on the legislative or executive functions of the State. They are non-justiciable principles that guide the government in the governance of the country. The limitations on the legislative and executive functions of the State are the fundamental rights enshrined in Part III of the Constitution.
