AnushaktiVidyut Nigam Limited is a joint venture of the Nuclear Power Corporation of India and

The correct answer is D) NTPC. Anushakti Vidyut Nigam Limited (ANVL) was incorporated in 2011 as a joint venture between NPCIL (Nuclear Power Corporation of India Limited) and NTPC. Its job is to build and operate nuclear power plants, so the partner is the thermal power major, not a hydro or mining PSU.

Why the others are wrong:

• A) NMDC is the National Mineral Development Corporation, a mining PSU under the Ministry of Steel. It has no role in nuclear power.
• B) NHPC is a hydro power PSU under the Ministry of Power. It is a tempting distractor because it is in the power sector, but it is not the ANVL partner.
• C) BHEL is Bharat Heavy Electricals Limited, an equipment manufacturer under the Ministry of Heavy Industries. It supplies plant equipment but is not a promoter of ANVL.

The core concept here is the PSU-to-PSU joint venture route for capacity addition in strategic sectors, with nuclear power kept under the Department of Atomic Energy and the Atomic Energy Act, 1962. For Mains, this ties into the debate on expanding nuclear capacity and the role of public sector partnerships in energy security.

Trap: aspirants pick NHPC or BHEL because both are famous power-sector PSUs. Remember that NTPC is the NPCIL partner in ANVL.
