It is actually C) U-Shaped Valley

Definition: U-shaped valleys, or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. They have a characteristic U shape, with steep, straight sides and a flat bottom. Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring.

The correct answer is letter B. V-shaped Valley. It is the evidence that an area was once covered by a glacier. Glaciers form in an area where the temperature is so very low and stayed there for a longer time. Glaciers that reached the oceans form icebergs.
