- Option 1, 1998: This year is not relevant to the enactment of PESA.

- Option 2, 1996: This is the correct year. PESA was indeed passed by the Indian Parliament in 1996.

- Option 3, 1995: There is no significant connection to PESA being enacted in this year.

- Option 4, 1993: In this year, the 73rd Constitutional Amendment Act was passed, which introduced the Panchayati Raj system in India but did not specifically address Scheduled Areas.
