Arêtes and pyramidal peaks: When two corries cut back on opposite sides of a mountain, knife-edged ridges are formed called aretes (a French word). A well-known British example of an arête is the Striding Edge on Helvellyn in Westmorland. Where three or more cirques cut back together, their ultimate recession will form an angular horn or pyramidal peak.

< b="" />Explanation:< />
The correct answer is option 'D', neither of them.
< b="" />Statement 1:< />
The statement is correct. When two corries cut back on opposite sides of a mountain, knife-edged ridges are formed called aretes. A corrie is a bowl-shaped hollow found on the side of a mountain, formed by glacial erosion. As the glaciers move down the mountain, they erode the sides of the corrie, creating steep knife-edged ridges called aretes. These aretes are often narrow and sharp, resembling the edge of a knife.
< b="" />Statement 2:< />
The statement is incorrect. When three or more cirques cut back together, their ultimate recession will not necessarily form an angular horn or pyramidal peak. A cirque is a bowl-shaped hollow found at the head of a glacier, formed by glacial erosion. As the glaciers move down the mountain, they erode the sides and bottom of the cirque, creating a steep-sided hollow. If three or more cirques cut back together, they may form a broad, rounded peak known as a horn. This is characterized by steep slopes on all sides. However, the ultimate shape of the peak will depend on various factors such as the nature of the rock, the direction of glacial movement, and the erosional processes involved. It is not necessary that it will always form an angular horn or pyramidal peak.
Therefore, both statements are not correct.
The correct answer is option 'D', neither of them.
