Answer: A (Andhra)

• Dhanyakataka (Dharanikota / Amaravati): Located on the banks of the Krishna River in the Andhra region.
• Historical Significance: It served as a major inland port, trading hub, and the eastern capital of the Satavahanas.
• Connection to Mahasanghikas: The region became the principal stronghold of the Mahasanghika school of early Buddhism and its offshoots (such as the Chaityakas, Purvasailas, and Aparasailas), which played a central role in patronizing and sculpting the Great Amaravati Stupa.

Key Facts (Buddhist Schools & Andhra Region):

• Mahasanghikas: Originated after the Second Buddhist Council (Vaishali) following a split with the Sthaviravadins (Theravadins). Their liberal, devotional doctrine laid the foundation for subsequent Mahayana Buddhism.
• Other Important Buddhist Sites in Andhra: Nagarjunakonda (Vijayapuri), Jaggayyapeta, Bhattiprolu, and Ghantasala.
