Lonar Lake is mainly believed to have formed due to which geographical cause?

Correct answer: Meteorite impact

Option C is correct because Lonar Lake is widely identified as an impact crater lake in Maharashtra. The governing concept is the origin of lakes: some form through glacial action, river deposition, tectonic movement, coastal processes or meteorite impacts. A large meteorite struck the basaltic surface of the Deccan region, producing a roughly circular depression that later collected water and became Lonar Lake. Glacial erosion is unlikely because the site is not a glaciated mountain environment. Tidal blocking applies to coastal settings, while river deposition generally creates floodplain or deltaic lakes rather than a distinctive crater basin. Thus the special geological origin points to a meteorite impact.
