Explanation:

To solve this, we analyze each option:

• Option A: An esker is a long, winding ridge of stratified sand and gravel formed by glacial meltwater, not a low point on an arête.
• Option B: A col is defined as a low point along an arête (a sharp ridge formed by glacial erosion) that acts as a pass between glacial valleys, which matches the description.
• Option C: A horn is a sharp, pyramid - like peak formed by the headward erosion of multiple glaciers, not a low - point pass.
• Option D: A drumlin is a streamlined hill formed by glacial deposition, not related to a low point on an arête.

Answer:

B. col
