Explanation by: Admin

Caldera lakes are formed when a volcano erupts and its magma chamber empties, causing the ground above to collapse and form a large crater (caldera), which then fills with water.

  • This is a common type of lake formed by volcanic activity.

Other options:

  • Lagoon: coastal water body separated by sandbars or reefs.
  • Freshwater lake: general term, not specific to volcanic origin.
  • Karst lake: formed by dissolution of soluble rocks like limestone.

So, volcanic lakes are specifically caldera lakes — option (C).
