Explanation:

• NCBC is statutory body established under NCBC Act, 1993 in the aftermath of Indra Sawhney vs. Union of India Case (Mandal Case) (1992) judgement.But 102nd Constitution Amendment Act, 2018 provides constitutional status to the National Commission for Backward Classes (NCBC).
• Act provides that the Commission shall consist of five Members, a Chairperson who is or has been a judge of the Supreme Court or of a High Court; a social scientist; two persons, who have special knowledge in matters relating to backward classes; and a Member-Secretary, who is or has been an officer of the Central Government in the rank of a Secretary to the Government of India.

Hence both statements are correct.
