Why Correct: The Damodar Valley Corporation (DVC) is a statutory body established under the DVC Act, 1948, jointly owned by the Government of India (50%) and the state governments of West Bengal and Jharkhand (25% each).
Distractor Analysis: A central government organization refers to entities like ONGC or NTPC, fully owned by the Government of India. A state government organization refers to entities like West Bengal State Electricity Distribution Company Limited, fully owned by a single state. An organization of only West Bengal and Jharkhand state governments would exclude the central government's ownership and control.
Takeaway: DVC was India's first multipurpose river valley project, modeled after the Tennessee Valley Authority (TVA) of the United States.
