The correct option is 2 and 4 only because both the Parishishta Parvan and Trishashtilakshana Mahapurana are recognized as important texts within the Jaina tradition. The Parishishta Parvan is considered a crucial scriptural work that deals with ancient Jaina narratives, while the Trishashtilakshana Mahapurana comprises stories of revered Jaina Tirthankaras. In contrast, the Nettipakarana is associated with Buddhist literature, and the Avadanasataka is primarily a collection of Buddhist stories. This distinction is critical in understanding India's diverse religious texts and their historical significance.
