Concept:Wind erosion in hot deserts sculpts rocks into distinctive landforms such as zeugens and rock pedestals.
Explanation:A zeugen forms where wind erodes a soft rock layer lying beneath a harder cap rock.
The result is a flat-topped tabular mass separated by parallel ridges and furrows.
A rock pedestal is a mushroom-shaped column whose lower base is worn narrow by airborne sand.
Its broader hard top protects the weaker base and gives the feature its distinctive shape.
To choose the correct option, test each pair for two genuine desert landforms.
Barchans are crescent-shaped desert dunes, but tombolos are coastal bars joining an island to the mainland, so option A is wrong.
Sand dunes may occur in deserts, yet tombolos remain coastal features, so option C is wrong.
Yardangs are desert ridges, but batholiths are large igneous intrusions found in many regions, so option D is wrong.
Option B contains the only pair in which both landforms result from wind action in desert areas.
Answer:Option B — Zeugens and rock pedestals.
