The National Commission for Scheduled Tribes
The National Commission for Protection of Child Rights
The National Commission for Minorities
This question was previously asked in
UPSC CISF-AC-EXE – 2024
The correct answer is B. Among the given options, the National Commission for Scheduled Tribes is a constitutional body.
– A constitutional body is one that is established by a specific provision of the Constitution of India.
– The National Commission for Scheduled Tribes (NCST) was established by Article 338A of the Constitution, inserted by the 89th Constitutional Amendment Act, 2003.
– The National Commission for Scheduled Castes (NCSC) was established by Article 338 of the Constitution (initially as a Special Officer, later constitutionalized). NCST was created by bifurcating the original NCSC.
– The National Commission for Backward Classes (NCBC) was initially a statutory body. It was granted constitutional status by the 102nd Constitutional Amendment Act, 2018, which inserted Article 338B.
– The National Commission for Protection of Child Rights (NCPCR) is a statutory body established under the Commissions for Protection of Child Rights Act, 2005.
– The National Commission for Minorities is a statutory body established under the National Commission for Minorities Act, 1992.
Given that both NCST (B) and NCBC (A) are currently constitutional bodies, this question might be considered flawed if it expects only one correct answer from a recent perspective. However, if the question originated before the 102nd Amendment Act of 2018, then NCBC would have been a statutory body, making NCST the only constitutional body among the options. Assuming the question is intended to have a single correct answer and may reflect an older context, B is the appropriate choice. If the question is from post-2018 and strictly asks for *a* constitutional body, then both A and B fit, but B is the most definitively correct answer that has been constitutional for a longer period. In typical UPSC style multiple-choice questions with a single best answer, there might be a historical context or a subtlety intended. Given the common pre-2018 questions in older test series materials, option B is the likely intended answer.
