Identify the primary historical and pragmatic rationale cited by the Constituent Assembly for classifying the Directive Principles of State Policy as non-justiciable:
1. A deliberate legal strategy engineered specifically to prevent constitutional friction and overlap with the Fundamental Rights chapter.
2. A structural mechanism designed to restrict the judiciary from encroaching upon the exclusive domain of the legislative branch.
3. An acknowledgment of the severe financial resource constraints and sweeping diversity that hindered the newly independent state's capacity to guarantee immediate welfare delivery.
