In what year did the Supreme Court deliver its ruling on the 'Indira Sawhney case'?

1992

The correct answer is Option 1 - 1992

 In August 1990, the National Front government decided to implement one of the recommendations of Mandal Commission pertaining to reservations for OBCs in jobs in the central government and its undertakings. This decision sparked agitations and violent protests in many cities of north India. The decision was also challenged in the Supreme Court and came to be known as the ‘Indira Sawhney case’, after the name of one of the petitioners. In November 1992, the Supreme Court gave a ruling upholding the decision of the government. There were some differences among political parties about the manner of implementation of this decision. But now the policy of reservation for OBCs has support of all the major political parties of the country.
