The correct answer is option 1 - 1

1) Sanchi was discovered later
2) Scholars found Sanchi to be more beautiful than Amravati
3) Sanchi's artifacts were less valuable
4) Amaravati was destroyed by natural disasters

Why did Sanchi survive while Amaravati did not? Perhaps Amaravati was discovered before scholars understood the value of the finds and realised how critical it was to preserve things where they had been found instead of removing them from the site. When Sanchi was “discovered” in 1818, three of its four gateways were still standing, the fourth was lying on the spot where it had fallen and the mound was in good condition. Even so, it was suggested that the gateway be taken to either Paris or London; finally a number of factors helped to keep Sanchi as it was, and so it stands, whereas the mahachaitya at Amaravati is now just an insignificant little mound, totally denuded of its former glory.
