D. It formed as weathered rock and soil was deposited in layers.
Sedimentary rocks are built up by deposition of sediments (weathered rock, soil, and organic material) in layers, which are later compacted and cemented. Lava cooling forms igneous rock, glaciers erode rather than create layered deposits, and faults cause breaks but don't create layered rock.
