​The Biodiversity Management Committees (BMCs) envisaged under the Biological Diversity Act (2002) and Rules (2004) are constituted at which one of the following administrative levels?​

Correct option is A

Explanation - 

Under the Biological Diversity Act, 2002 and the Biological Diversity Rules, 2004, Biodiversity Management Committees (BMCs) are:
Constituted at the local body level, which includes:
                                                           Village Panchayats
                                                           Municipalities
                                                           Municipal Corporations
These are the grassroots administrative units, and the primary level of governance in the decentralized system.
Role of BMCs: Document biological resources and associated traditional knowledge in a register known as the People’s Biodiversity Register (PBR).
                           Advise the State Biodiversity Board (SBB) and National Biodiversity Authority (NBA).
                           Ensure local participation in conservation and sustainable use of biodiversity.

Incorrect options-
Option b - Tehsil/Taluka : This is a sub-district administrative unit but not where BMCs are directly constituted.
Option c - District : Biodiversity-related governance at the district is managed by State Biodiversity Boards, not BMCs.
​Option d - State : States have State Biodiversity Boards (SBBs), not BMCs.

So, the correct answer is option a - Village
