C Correct answer
Explanation

In geomorphology, deflation (removal of fine particles by wind) and abrasion (rock grinding by friction) are the two primary mechanical actions of wind erosion in topography. Attrition involves reduction in particle size through collisions but is more associated with fluvial (river) processes. Corrosion refers to chemical weathering, which is not classified as a topographic action in the same mechanical sense.
