Option A is correct.
Dhanyakataka, also known as Amaravati, was a prominent city and a significant Buddhist center located in the Andhra region of ancient India. It flourished under the patronage of the Satavahanas and later the Ikshvakus and was associated with the Mahasanghika school of Buddhism, known for its famous stupa.
Dhanyakataka was situated on the banks of the Krishna River in present-day Andhra Pradesh. It was a major urban, religious, and trade center. The Great Stupa at Amaravati is renowned for its exquisite sculptures illustrating Buddhist themes. While Gandhara (in the northwest), Kalinga (modern Odisha), and Magadha (modern Bihar) were also significant regions with Buddhist connections at various times, Dhanyakataka’s location is firmly established in the Andhra region.
