1. A

   1 only

   1 only. Incomplete. Location in the lower Krishna valley is correct, but statement 3 on the lasting sculptural influence and overseas reach is also correct.

2. B

   1 and 3 only

   1 and 3 only. Correct. Amaravati belongs to the lower Krishna valley, and the Amaravati school shaped later South Indian sculpture with products carried to Sri Lanka and South-east Asia. Statement 2 is not accepted as correctly worded.

3. C

   2 and 3 only

   2 and 3 only. Incorrect. It keeps the doubtful size comparison with Sanchi and drops the secure location fact.

4. D

   1, 2 and 3

   1, 2 and 3. Incorrect because statement 2 does not stand as a reliably correct claim in the standard reading.

Summary. Official key is (b): statements 1 and 3 hold; the “next only to Sanchi in size” claim does not.
