Explanation
The correct option is IPS officers are assigned to a particular State cadre.
The Indian Police Service (IPS) is an All India Service (AIS) constituted under Article 312 of the Constitution. The structure of AIS is designed to ensure a unified administration while respecting the federal setup.
- IPS officers are assigned to a particular State cadre. is Correct: Upon recruitment, IPS officers are allocated to a specific State cadre (or a Joint Cadre like AGMUT). They serve within this cadre for the majority of their career, although they remain liable to serve the Union Government. There is no separate "Central Cadre" for the IPS.
- IPS officers are recruited by the State Public Service Commissions. is Incorrect: IPS officers are recruited by the Union Public Service Commission (UPSC) through the Civil Services Examination, not by State Public Service Commissions. State PSCs recruit for State Services (e.g., State Police Service).
- IPS officers cannot be deputed to the Central government. is Incorrect: IPS officers can be and are frequently deputed to the Central Government under the Central Deputation Reserve (CDR). They hold positions in Central Armed Police Forces (CAPFs), intelligence agencies (IB, RAW), and other central organizations.
- IPS officers are under the disciplinary control of the State government. is Incorrect: The disciplinary control over All India Services is divided. The State Government exercises immediate control (e.g., transfers, posting, suspension), but the ultimate control (e.g., dismissal, removal, or reduction in rank) lies with the Central Government (Ministry of Home Affairs for IPS).
Key Takeaway: All India Services (IAS, IPS, IFoS) are characterized by recruitment by the Centre, allocation to State cadres, and a system of dual control where immediate authority lies with the State and ultimate disciplinary authority lies with the Centre.
