The correct answer is: C. The year 1979.
The Mandal Commission was a commission set up by the Government of India in 1979 to identify the socially and educationally backward classes in India. The commission was headed by B. P. Mandal, a former Chief Justice of India. The commission submitted its report in 1980, which recommended that 27% of government jobs and seats in educational institutions be reserved for members of the Other Backward Classes (OBCs). The report was controversial, and its recommendations were not implemented until 1990.
The other options are incorrect because:
- Option A is incorrect because the first Backward Class Commission was appointed in 1953.
- Option B is incorrect because the second Backward Class Commission was appointed in 1979.
- Option D is incorrect because the third Backward Class Commission was appointed in 2005.
