At what level do Panchayat Samities exist in India?

Concept: India's rural local self-government generally follows a three-tier Panchayati Raj structure created by the 73rd Constitutional Amendment Act, 1992 -- the Gram Panchayat at the village level, the Panchayat Samiti at the intermediate (block) level, and the Zila Parishad at the district level. Under Article 243B, a state with a population not exceeding twenty lakh may choose not to constitute the intermediate tier, but where it does exist, it takes the form of the Panchayat Samiti at the block level.

Application: A Panchayat Samiti is constituted for each block and functions as the middle tier of this structure, sitting between the village-level Gram Panchayat and the district-level Zila Parishad. This block-level placement is codified in state Panchayati Raj legislation (for example, the Tripura Panchayats Act, 1993) and matches TPSC's official answer key for this question, which marks 'Block' as the correct option.

Cross-check: Testing each level against the three-tier structure confirms this placement:

• Village level is occupied by the Gram Panchayat, the base tier below the block -- not the Panchayat Samiti.

• District level is occupied by the Zila Parishad, the apex tier above the block -- not the Panchayat Samiti.

• 'None of these' is ruled out because, where the three-tier structure applies, it places the Panchayat Samiti at exactly one level, and that level is offered among the options.

So the Panchayat Samiti exists at the block level, confirming Block as the correct answer.
