    Correct Answer: B

    Solution :

     A cirque is an amphitheater-like valley head, formed at the head of a valley glacier by erosion. Yardang is a keel-shaped crest or ridge of rock, formed by the action of the wind usually parallel to the prevailing wind direction. Barkhan is a crescent-shaped shifting sand dune convex on the windward side and steeper and concave on the leeward. It is an erosional feature of wind. Drumlin is a long, narrow or oval. Smoothly rounded hill of un stratified glacial drift. Domains arc generally found in broad lowland regions, with their long axes roughly parallel to the path of glacial flow.
