A Joint Public Services Commission for two or more States can be established by

1. A

   Union Public Services Commission

   Option (a) claims the Union Public Services Commission can establish a Joint Public Services Commission. The UPSC conducts examinations for all-India and central services, but it does not have the constitutional authority to create joint state bodies.

2. B

   Parliament if requested by concerned states

   Option (b) claims that the Parliament can establish a Joint Public Services Commission if requested by the concerned states. According to Article 315 of the Constitution of India, a Joint Public Service Commission for two or more states can be created by an act of Parliament upon a resolution passed by the legislatures of those states, making this the correct option.

3. C

   Rajya Sabha

   Option (c) claims that the Rajya Sabha alone can create a Joint Public Services Commission. While the upper house holds special powers regarding state lists and all-India services under Article 312, it does not unilaterally establish joint public service commissions for states.

4. D

   Lok Sabha

   Option (d) claims that the Lok Sabha can establish a Joint Public Services Commission. The establishment of such a body requires a formal legislative enactment by the entire Parliament based on state requests, not just an action by the lower house.

Summary. Official key is (b) Parliament if requested by concerned states. Article 315 provides the constitutional basis for establishing a Joint Public Service Commission for two or more states through an act of Parliament. This requires a formal request made through resolutions passed by the legislatures of the respective states. Neither the UPSC nor a single house of Parliament possesses the unilateral authority to create this inter-state body. Therefore, option (b) is the correct choice as it accurately reflects the constitutional procedure.
