Explanation –

Statements 1 and 2 are incorrect. The census is a Union subject in the Union List of the Seventh Schedule of the Constitution. Only the Centre is entitled to conduct a census. However, under the Census Act of 1948, states can collect population data for various purposes such as implementing welfare schemes. However, states cannot conduct a full-fledged census independently. The 10% reservation for economically weaker sections (EWS) is not given to the OBCs, SCs, and STs. It is specifically meant for individuals who are not covered under the existing reservations for SC, ST, and OBC categories​.

Statement 3 is correct. The Constitution provides for reservations in electoral constituencies in panchayats and municipalities for OBCs but does not provide reservation to OBCs in electoral constituencies for MPs and MLAs. While SCs and STs have reserved constituencies at all levels, such provisions for OBCs are only at the local government level​.
