The correct answer is Drumlins.

“Basket-of-eggs topography” is a descriptive term used for landscapes characterized by a large number of drumlins. Drumlins are streamlined, elongated hills formed by glacial ice acting on underlying unconsolidated material. They are typically shaped like an inverted spoon or half-buried egg, with the blunt end facing upstream (towards the ice flow) and the tapered end pointing downstream. When numerous drumlins are present together in a region, they create a distinctive pattern resembling a basket filled with eggs from an aerial view.

Eskers are ridge-like deposits left by meltwater streams within or under a glacier. Cirques are bowl-shaped depressions carved by glacial erosion at the head of a valley. Moraines are accumulations of rock debris deposited by glaciers, forming various features like ridges (lateral, medial, terminal moraines) or irregular deposits (ground moraine). Only drumlins occur in clusters that create the “basket-of-eggs” appearance.
