Provision for appointment of National Commission for SC’s and ST’s has been made in the Constitution under article.

The answer is A. Article 338 provides for the National Commission for Scheduled Castes, and Article 338A, inserted by the 89th Amendment (2003), provides for the National Commission for Scheduled Tribes. Before 2003, a single Special Officer under Article 338 handled both groups. The 89th Amendment split the body into two commissions with constitutional status.

Why the others fail:

• B) 337 deals with special provision for Anglo-Indian education in states, not with any commission.
• C) 334 is the sunset clause on reservation of seats in the Lok Sabha and state assemblies and on special representation, originally for ten years and extended repeatedly.
• D) 339 covers the Union's directions on administration of Scheduled Areas and welfare of Scheduled Tribes. It is a different subject from setting up a commission.

Core concept: constitutional safeguards and institutional mechanisms for SCs and STs. This links directly to Mains GS-II on welfare bodies and their accountability. Since the 102nd Amendment (2018), Article 338B governs the structure and functions of both commissions, and Article 338 deals with the NCSC alone. The 2013 question tested the 338 and 338A pairing.

Trap: candidates pick 339 because it sounds like the tribal provision, or choose a single article and forget that the STs commission has its own separate article.
