Which of the following pairs of landforms are of desert origin

To identify a pair of landforms that are both of desert origin, each feature must be formed primarily by arid-environment processes such as wind erosion, wind deposition, or weathering in dry climates.

• Zeugens are tabular rock formations created by wind abrasion in deserts. The wind erodes softer rock layers more rapidly than harder cap layers, producing mushroom-shaped or flat-topped pedestals.
• Inselbergs are isolated steep-sided residual hills or rock outcrops that rise abruptly from a surrounding flat plain. They are characteristic of arid and semi-arid landscapes, formed through long-term weathering and erosion that strips away surrounding rock while the more resistant core remains.

Both zeugens and inselbergs are classic desert landforms.

The other pairs include at least one non-desert feature:

• Batholiths are large igneous intrusions formed deep underground, not a surface desert feature.
• Tombolos are coastal landforms (sand ridges connecting an island to the mainland), formed by wave deposition.
• Sandbars are also coastal or riverine depositional features.

The correct answer is zeugens and inselbergs.
