- rock fragments slide down a pre existing surface

The correct answer is option a, that is, the sediment and rock fall off a slope in concave curves.

A slump refers to a kind of mass wasting, which takes place when a coherent mass of loosely consolidated layers of rock or materials moves a short distance down a slope. The movement is featured by sliding along a concave-upward or planar surface.

The reasons for slumping involve freezing and thawing, earthquake shocks, thorough wetting, undercutting, or loading of a slope.
