    Answer : Option A

    Explanation :

    A crater lake is a depression created by a volcanic crater or caldera that is filled with water. When a volcano is no longer active, the crater or caldera may fill with water from rainfall and melting snow that may also feed the lake. A lake can also exist in an impact crater, created by the fall of a meteor or in one case a nuclear weapon test in Kazakhstan. Sometimes these are also called crater lakes.
