Which one of the following is NOT correctly matched ?

The correct answer is D. Article 48 deals with organisation of agriculture and animal husbandry on modern and scientific lines, including preservation of cattle and prohibition of slaughter of cows, calves and other milch and draught cattle. Separation of judiciary from executive is Article 50, a Directive Principle under Part IV.

Checking the others: Article 39A (inserted by the 42nd Amendment, 1976) directs the State to promote equal justice and provide free legal aid so that no citizen is denied justice for economic or other disabilities. Article 40 asks the State to organise village panchayats and endow them with the powers needed for self-government. Article 44 directs the State to secure a Uniform Civil Code for citizens. It remains a Directive Principle and has not been enacted nationally.

The core concept is the Directive Principles of State Policy, which are non-justiciable guidelines for the State. Articles 39A and 50 are often confused because both concern the justice system, but only Article 50 deals with separating the judiciary from the executive. For Mains, this connects to the debate on judicial independence and the functioning of the subordinate judiciary in the states.

Trap: Aspirants remember "separation of judiciary" as the first DPSP that comes to mind and attach it to 48 or 39A. Keep the numbering anchored: 39A is legal aid, 40 is panchayats, 44 is UCC, 48 is agriculture and cattle, 50 is separation.
