Explanation:

Bergschrund is a depositional landform feature formed due to the movement of glaciers: This statement is incorrect. A bergschrund is actually a crevasse or crack that forms at the top of a glacier where the moving ice separates from the stagnant ice or rock below. It is an erosional feature, not a depositional one.

The depositional equivalent of erosional knob-and-tail structures are known as drumlin: This statement is incorrect. Knob-and-tail structures are erosional landforms, and the depositional equivalent is not a drumlin but a roche moutonnée.

Eskers are long, narrow, sinuous ridges composed of sand and gravel: This statement is correct. Eskers are depositional landforms created by meltwater streams flowing within or beneath glaciers. They are composed of sand and gravel and often form long, winding ridges.
