Hint - All kinds of debris fall onto the glacier through mechanical weathering of the canyon walls, as glaciers flow over the years. Glaciers are solid ice, so unlike water, they can carry pieces of rock of any size. Glaciers move as easily as a house with the smallest particles of sand and silt. These pieces of rock are carried by the glacier for several kilometers and are deposited only as the ice melts. When you think of a glacier, you can think of white snow and ice, but in fact the glaciers contain a lot of rocky bits. Each of these different deposits has its own name depending on where it is formed, but as a group they are called moraines.

Complete answer: Glacier landforms are landforms created by the action of glaciers. Most of today's glacial landforms were formed by the movement of large ice sheets during the Quaternary glaciers. Some regions, such as Phenoscandia and the Southern Andes, are widespread occurrences of glacial landscape; Other areas, such as the Sahara, exhibit rare and very old fossil glacial landforms.
As glaciers expand, due to their accumulated weight of snow and ice, they crush and destroy surfaces such as rocks and bedrock. The resulting erosive landforms include striations, serics, glacial horns, arights, trim lines, U-shaped valleys, roaches, moutney, overdiping, and hanging valleys.
When the glaciers retreated leaving their cargo of crushed rock and sand (glacial drift), they created characteristic reflective landforms. Examples include glacial moraine, escars and kamesh. Drumlin and Ribbed Moren are also landforms left over from glacier retreats. The stone walls of New England have many glacial erratics, rocks that a glacier dragged from several original bases.
Esker: A bed built of a subclass stream.
Low: irregularly shaped mound.
Moraine: The feature may be terminal (at the end of a glacier), lateral (along the edges of the glacier), or medial (formed by the merging of lateral mortars from the contributing glaciers).
Outwash Fan: A stream flowing from the front end of a glacier.

So option B is the correct answer.

Note - In addition to the terrain left behind by glaciers, glaciers themselves can be striking features of terrain, particularly in the polar regions of the Earth. Notable examples include glaciers of the valley where glacial flow is restricted by valley walls, crevasses in the upper reaches of glaciers and waterfalls ice equivalent to waterfalls.
