Which of the following is NOT one of the four categories under which the…

Concept. Part IV of the Constitution (Articles 36 to 51) holds the Directive Principles of State Policy — directives that are not enforceable by any court but that guide the State when it frames laws and policy. The Constitution itself lays down no classification for them; standard commentaries group them by the ideology or the subject matter each directive expresses. The four-fold grouping that this classification uses is: economic and social principles, Gandhian principles, principles and policies relating to international peace and security, and a residuary miscellaneous (liberal-intellectual) group.

Application. Each offered heading is now matched against that four-fold grouping, using the Articles that fall under it:

Three of the offered headings — economic and social principles, Gandhian principles, and principles and policies relating to international peace and security — appear in that grouping word for word. "Cultural heritage principles" does not appear as a heading at all. Heritage protection is present in Part IV as a single directive, Article 49, and that Article is placed inside the residuary miscellaneous group; it is never raised to a category of its own.

Cross-check and contrast. The stem's words "the four categories" anchor the four-fold scheme, and that anchoring carries weight, because a second classification is also widely taught — the three-fold scheme of socialistic, Gandhian and liberal-intellectual principles:

• Socialistic principles — the economic and social directives, Articles 38, 39, 39A, 41, 42, 43, 43A and 47.

• Gandhian principles — Articles 40, 43, 43B, 46, 47 and 48.

• Liberal-intellectual principles — Articles 44, 45, 48, 48A, 49, 50 and 51.

The three-fold scheme cannot settle this item on its own, because it folds Article 51 on international peace and Article 49 on monuments into the same liberal-intellectual head; under it neither "principles and policies relating to international peace and security" nor "cultural heritage principles" survives as a standalone heading. The stem must therefore be read against the four-fold scheme, in which international peace and security is raised to a category of its own while heritage protection is not. What the three-fold scheme does confirm is the direction of the contrast: in every published classification Article 49 is absorbed into a broader head and never given a heading of its own, whereas the Gandhian head and the economic-and-social head appear in every scheme. Hence "Cultural heritage principles" is the heading that is not one of the four categories.

Exam tip. Article 51 is the lone international-relations directive and Article 49 the lone monuments directive in Part IV. Only the four-fold scheme promotes Article 51 to a category of its own; no published scheme ever promotes Article 49.
