This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
The correct answer is C. Glacier
Explanation
In the image, you can see the water cycle, and there are four letters, A, in the part of the sea; B on the earth's surface; the C below the Earth's surface, and the D in the mountains. In the area where the D is, there are glaciers on the mountain peaks caused by the low temperatures in the area. In addition, a glacier is a mass of ice formed on the earth's surface by the accumulation of snow on mountain peaks, in Antarctica, the Arctic, and Greenland. Therefore, the correct answer is C. Glaciar.
