Exp) Option a is the correct answer

The Constitution requires the president to appoint a commission to report on the administration of the scheduled areas and the welfare of the scheduled tribes in the states. He can appoint such a commission at any time but compulsorily after ten years of the commencement of the Constitution. Hence, a commission was appointed in 1960. It was headed by U.N. Dhebar and submitted its report in 1961. After four decades, for the same purpose, the second commission known as Scheduled Areas and Scheduled Tribes Commission, was appointed in 2002 under the chairmanship of Dilip Singh Bhuria. The Commission was tasked with investigating and reporting on the problems of the Scheduled Tribes (STs) in India, formulating a comprehensive tribal policy and outlining a vision for the future of STs. It submitted its report in 2004.
