Correct option is A

The correct answer is: (a), A and E only
Yardang is a landform created by wind erosion, typically found in arid regions, characterized by elongated ridges or hills aligned with the prevailing wind direction.
Stumps are eroded remnants of rock formations, often found in coastal areas where wave action has worn away softer rock, leaving behind isolated columns or pillars.
Structural bench is a flat, horizontal surface or terrace formed by tectonic activity, erosion, or deposition along a geological fault or fold.
Col, also known as a mountain pass, is a saddle-like depression or notch in a mountain ridge, formed by erosion from glaciers or water. It provides a route for crossing from one side of the mountain to the other.
Information booster
Arete is a narrow ridge formed by the erosion of adjacent glacier valleys, resulting in a sharp, steep-sided ridge between them.
Esker is a long, winding ridge of gravel and sediment deposited by streams flowing within or beneath glaciers. Eskers are typically formed during glacial retreat.
Cirque are the erosional landforms of glaciers. They are simply the bowl shaped depression formed due to the erosional activity of glaciers.
Barchans are crescent shaped dune whose long axis is transverse to the dominant wind direction. The points of the dune, called the wings of the barchan, are curved downwind and partially enclosing the slip face.
Blow hole is a coastal landform created by wave erosion, characterized by a hole or cave in a sea cliff through which water and air are forced upward.
Sief dune large pyramiodal or star shaped dune with three or more sinuous ridge radiating ridges form a central peak of sand. This dune has 3 or more slip faces. Produced by variable winds.
