(d) 1, 2 and 3

Answer : B

Explanation:

Statement I is correct: The Amaravati Stupa (historically known as the Mahachaitya) was built in the lower Krishna River valley in modern-day Andhra Pradesh, flourishing under the patronage of the Satavahanas and Ikshvakus.
Statement II is not correct: The Amaravati Stupa was actually larger than the Sanchi Stupa. At its zenith, its massive dome diameter reached approximately 50 meters, surpassing the dimensions of Sanchi's Great Stupa (which is around 36 meters in diameter).
Statement III is correct: The dynamic, narrative style of the Amaravati School of Art deeply influenced subsequent South Indian dynastic art forms (like Pallava and Chola sculptures). Due to maritime trade networks, its distinctive white/greenish limestone sculptures and styles were also carried over to Sri Lanka and across Southeast Asia.
