As I said in your other post/question on the same topic, you have to rephrase your question in order for us to help you. =)
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.
