Sanghabhuti, an Indian Buddhist monk, who travelled to China at the end of the fourth century AD, was the author of a commentary on:

The correct answer is Option 3.

Key Points

• The Indian Buddhist monk who traveled to China around 400 AD, was known for his commentary on the Sarvastivada Vinaya. This text outlines the monastic code of conduct for the Sarvastivada school of Buddhism. Hence correct answer is Option 3.
• Prajnaparamita Sutra: This Mahayana Buddhist text focuses on the concept of Prajna (wisdom). While Sanghabhuti might have been familiar with this text, there's no historical evidence linking him specifically to a commentary on it.
• Visuddhimagga: This Theravada Buddhist text focuses on the path to liberation. It's unlikely that Sanghabhuti, associated with the Mahayana tradition, would have written a commentary on a Theravada text.
• Lalitavistara: This Mahayana Buddhist text elaborates on the life of Buddha. Similar to the Prajnaparamita Sutra, there's no specific link between Sanghabhuti and a commentary on this text.
