- Statement 1 is correct. The National Commission for Scheduled Tribes was established as a separate constitutional body under Article 338A by the Constitution (Eighty-ninth Amendment) Act, 2003, splitting the original National Commission for Scheduled Castes and Scheduled Tribes. - Statement 3 is correct. The National Commission for Women was constituted as a statutory body under the National Commission for Women Act, 1990. It is not a constitutional body. - Statement 2 is incorrect. The National Commission for Backward Classes (NCBC) was given constitutional status by the 102nd Amendment Act, 2018 (adding Article 338B). The National Commission for Scheduled Castes (NCSC) is a constitutional body (Article 338). However, the National Commission for Minorities is a statutory body, established under the National Commission for Minorities Act, 1992. Since the statement claims all three (NCBC, NCM, and NCSC) are constitutional bodies, it is incorrect.
