C Correct answer
Explanation

Synclines are downward-arching folds in rock layers (U-shaped) formed by crustal compression, where tectonic forces push rock layers together horizontally. Unlike rifting (tensional forces pulling apart) or faulting (fracture and displacement), compression causes bending and folding without breaking, creating alternating synclines and anticlines.
