With reference to Indian history, consider the following texts:

1. Nettipakarana
2. Parishishtaparvan
3. Avadanashataka
4. Trishashtilakshana Mahapurana Which of the above are Jaina texts?

Nettipakarana is a Buddhist scripture, a guide attributed to Buddha's disciple Kaccana to help understand and present Buddhist teachings.

Avadanasataka are texts that emerged possibly between the 2nd century AD and the 11th century AD and are associated with Buddhism.

Parishishtaparvan, also known as Sthaviravalicharitra, is a 12th-century Sanskrit mahakavya by Hemachandra, detailing the history of early Jain teachers.

Mahapurana or Trishashthilkshana Mahapurana is a major Jain text primarily composed by Acharya Jinasena during the Rashtrakuta ruler Amoghavarsha's reign and completed by his pupil Gunabhadra in the 9th century CE.

Therefore, Parishishtaparvan and Trishashtilakshana Mahapurana are Jaina texts.

Hence, option (b) is the correct answer.
