The Directive Principles of State Policy (DPSP) are guidelines for the State's governance aimed at ensuring social and economic justice and welfare. They do not impose formal limitations on the legislative or executive functions; instead, they serve as directives for policy-making to guide laws and actions towards achieving constitutional goals. Thus, the correct interpretation is that they do not limit but rather enhance the responsibilities of these branches of government, making the option "Neither 1 nor 2" correct. This distinction is crucial for understanding the balance between Part III (Fundamental Rights) and Part IV (DPSP) of the Constitution, as both are meant to complement each other in fostering a just society.
