Concept:Denudation is the wearing away of the Earth’s surface by agents such as wind, water, ice, and waves.
Explanation:Denudation includes weathering, erosion, transportation, and deposition.
Wind is a direct agent of erosion, especially in arid regions, where it transports sand and dust.
Insolation causes heating but is not itself an agent of denudation.
Energy and gravity are forces, not classified as denudation agents in this context.
Therefore, wind is the agent of denudation among the options.
Answer:B. Wind
