{'glacial topography': [0, 0, 1, 0], 'topography': [1, 0, 1, 1], 'fluvial': [1, 0, 1, 2], 'desert': [0, 0, 0, 1], 'potholes': [0, 0, 1, 0], 'col': [0, 0, 1, 0], 'cirque': [0, 0, 1, 0]}

The correct answer is option 1.

Option 1 is correct because a cirque is a feature found in glacial topography. It is a bowl-shaped hollow created by a glacier`s erosive action. A col, on the other hand, is a low point or pass between two mountain peaks or ridges in a glaciated area.

Option 2 is incorrect because barkhans and yardangs are features found in desert topography, not together. Barkhans are crescent-shaped sand dunes formed by wind, while yardangs are elongated, streamlined ridges carved by wind erosion.

Option 3 is incorrect because eddies and potholes are features found in fluvial (river) topography, not together. Eddies are swirling currents of water, while potholes are cylindrical holes carved into the riverbed by the erosive action of the water.

Therefore, the correct pairs are cirque and col in glacial topography, making option 1 the correct answer.
