The correct option is A glacial moraines
Glaciers pick up a lot of sediments as they move through valleys. The glaciers bulldoze sediments like rocks, sand and silt. Once the glaciers stop in a place, they deposit all these sediments. As the temperature increases, the ice melts and all the sediments get deposited. The landforms that are created when these sediments get deposited over and over for many years are called moraines.
