Which on of the following is not a Constitutional body?

The correct answer is D) Planning Commission. It was set up by a Cabinet resolution of 15 March 1950, not by the Constitution, so it has no constitutional status. It was replaced by NITI Aayog on 1 January 2015, a change that came after your exam year.

• A) UPSC: Part XIV, Article 315 provides for a Union Public Service Commission.
• B) State PSC: Article 315 also provides for a Public Service Commission for each state.
• C) Finance Commission: Article 280 requires the President to constitute it to recommend the distribution of taxes between the Centre and the states.

The core concept is the difference between constitutional bodies, which are created by the Constitution and have defined functions and protected tenure, and bodies created by ordinary law or executive order. This matters for Mains GS-2 on institutional design and for GS-3 on fiscal federalism, where the Finance Commission is central.

Trap: Aspirants often assume that any body important to governance must be constitutional. Others wrongly mark the Finance Commission as non-constitutional because it is not a permanent body, but its basis lies in Article 280.
