List I List IT List III List IV

The correct answer is Option 1. In the context of the Indian Constitution and the UPSC framework, matching these lists requires aligning constitutional provisions with their corresponding articles and sources.

• C - Directive Principles of State Policy (DPSP): These are contained in Part IV of the Constitution. Therefore, C matches with 4.
• I - Irish Constitution: The DPSP were famously borrowed from the Constitution of Ireland. Thus, the category matches with source I.
• (iii) - Article 36-51: These specific articles define the scope and application of the Directive Principles. This confirms the sequence C-4-I-(iii).

Other options are incorrect because they mismatch the parts or sources. For instance, Option 2 links "D" (Fundamental Duties) with Part 3, whereas Fundamental Duties belong to Part IV-A. Option 1 provides the only logically consistent alignment between the subject matter, the constitutional part, the historical source, and the article range.
