A caldera lake, which is formed by volcanic activities, is the correct answer.
Option 1: Caldera lake is formed when a volcano collapses into itself, leaving behind a large, deep crater. This crater fills with water, creating a caldera lake.
Option 2: Karst lake is formed in limestone or dolomite landscapes due to the dissolution of underground rock.
Option 3: Lagoon is a shallow body of water separated from a larger body of water, such as a sea or ocean, by barrier islands or reefs.
Option 4: Freshwater lake refers to any lake that contains freshwater, regardless of its formation process.
In summary, caldera lakes are specifically formed by volcanic activities, while other options describe lakes formed by different processes.
