Which primary feature results when aeolian Abrasion transforms desert rocks?

A)Ventifact formation on exposed surfaces
B)Lateral migration shifts of barchan dunes
C)Dissolution widens limestone karst cliffs
D)Suspension concentrates silt to fertile soil

💡 Explanation

Ventifacts' angular shapes on rocks form because aeolian abrasion, caused by wind-blown particles, erodes rocks. The wind selectively polishes and sculpts exposed surfaces; this mechanism is "abrasion", therefore, ventifacts appear, rather than dune migration or karsts.
