Explanation:

The National Commission for SCs is also required to discharge similar functions with regard to  the other backward classes (OBCs) and the  Anglo-Indian Community  as  it does  with  respect to the  SCs. In other words, the Commission has to investigate all matters relating to  the constitutional and other legal safeguards for the OBCs and the Anglo-Indian Community and report to the President upon their working. Hence option 2nd is correct.
