Residual soils are formed by

Answer: Option D

Residual soils are formed by the weathering and decomposition of rocks at the same place where they originally existed. They remain at their place of formation and are not transported by external agents.

Agents such as glaciers, wind, and water are responsible for transporting soils from one location to another, producing transported soils rather than residual soils.

Therefore, residual soils are not formed by glaciers, wind, or water, making Option D the correct answer.
