Final answer:

The glacial feature in question is most likely a horn, which is a pointed, mountain peak formed by the erosion of glaciers, and is present in regions like Torres del Paine.

Step-by-step explanation:

To answer the student's question about the naming of a glacial feature, we will need to assess the options presented: a) Tarn, b) Horn, c) Arete, and d) Cirque. A tarn is a mountain lake, pond, or pool, formed in a cirque excavated by a glacier. A horn is a pointed, mountain peak, typically pyramidal in shape, bounded by the walls of three or more cirques. An arete is a narrow ridge of rock which separates two valleys, typically formed when two glaciers erode parallel U-shaped valleys. A cirque, also known as a corrie or cwm, is an amphitheatre-like valley formed by glacial erosion. This feature is typically situated on the side of a mountain and may contain a tarn at its base.

Based on Figures 8.11 and 15.3.1, the student is most likely referring to a horn, which is present in mountain regions like Torres del Paine, where sharp mountain peaks have been sculpted by glaciers.
