In the Constitution of India, the category of Other Backward Classes (OBCs) is described as "Socially and Educationally Backward Classes." This classification aims to provide affirmative action in the form of reservations for people who belong to communities that are socially and educationally disadvantaged in society.
This classification is recognized under Article 15(4) and Article 16(4) of the Indian Constitution, which allow the state to make special provisions for the advancement of socially and educationally backward classes of citizens.
The other options, such as "Socially and Economically backward classes" or "Socially and Politically backward castes," are not the terminology used in the Constitution.
