Q. These specific landforms are depositional features of Glaciers. They are smooth oval-shaped ridge-like features composed mainly of glacial till with some masses of gravel and sand. They are also known as a basket of eggs topography. These landforms are:

The correct option is B Drumlins
Explanation:
Drumlin, oval or elongated hills are believed to have been formed by the streamlined movement of glacial ice sheets across rock debris, or till. They are arranged diagonally and so are commonly described as having basket of eggs topography.
Drumlins are generally found in broad lowland regions, with their long axes roughly parallel to the path of glacial flow. Although they come in a variety of shapes, the glacier side is always high and steep, while the lee side is smooth and tapers gently in the direction of ice movement. Drumlins can vary widely in size, with lengths from 1 to 2 km (0.6 to 1.2 miles), heights from 15 to 30 m (50 to 100 feet), and widths from 400 to 600 m. Most drumlins are composed of till, but they may vary greatly in their composition. Some contain significant amounts of gravels, whereas others are made up of rock underlying the surface till (rock drumlins). Drumlins are often associated with smaller, glacially streamlined bedrock forms known as roches moutonnées.
