The term mass wasting describes "down slope movement of a landslide".

Option: D

Explanation:

Mass loss or wasting is understood as slope motion or mass movement, it is the geomorphic mechanism through which regolith, soil, sand and rock travel downslope usually as a solid, continuous, or discontinuous mass, generally below the force of gravity, often with flow properties as in debris flows and mud flows.

Falls, rotational and translational slides, fluxes, and creep seem to be the most common types of mass-wasting. Falls are sudden movements of rock detaching itself from steep slopes or cliffs. Separate the rocks around known natural breaks like fractures or bedding planes. Movements occur as free-falls, bounces and rolls.
