The correct answer is - c. the highest lake in the world located near its peak.
Navado Ojos del Salado is the place where we have the highest lake in the world. It is a lake of glacial origin. When the glaciers were retracting, and the climate was getting warmer, in a depression in the highest parts some of the ice melted and became liquid water, thus filling the depression with it, and creating a lake.
