Weathering and erosion are not the constructive forces on Earth's surface.
Options C and D are the correct answers.
Constructive forces are the processes that lead to the creation of a new landform or up-gradation of the existing one.
Constructive forces can be the volcanic eruptions that form islands, the deposition of sediments forming sand dunes and deltas, and the collision of tectonic plates forming the mountains. The destructive forces lead to the destruction and deterioration of the landforms which can be in the form of weathering or erosion.
Therefore, the wind and water are the only constructive forces present on the surface of the Earth.
