Which of the following statements on the Amaravati Stupa and its relief sculpture is/are correct? 1. It was located in the lower Krishna valley. 2. In India, it was next only to the Sanchi Stupa in size. 3. The Amaravati school of sculpture made a lasting impact on the later South Indian sculpture, and its products were carried to Sri Lanka and South-east Asia.

The Amaravati Stupa was situated in the lower Krishna valley in present-day Andhra Pradesh, so statement 1 is correct. Statement 3 is also correct — the Amaravati school of sculpture deeply influenced later South Indian art (Pallava, Chola) and its style spread to Sri Lanka (Anuradhapura) and South-East Asia (Indonesia, Thailand). Statement 2 is incorrect: Amaravati was not next only to Sanchi; in fact, the Amaravati Mahachaitya was one of the largest stupas in India and the comparison with Sanchi is not historically accurate in that order. Hence 1 and 3 only.
