This type of rock is made of fragments (ex. conglomerate, sandstone, shale).

Explanation:
Fragments from other rocks indicate a clastic rock. Clastic rocks form when pieces (clasts) of preexisting rocks are produced by weathering and erosion, then transported, deposited, compacted, and cemented into a new rock. Conglomerate, sandstone, and shale are classic examples, each built from different-sized fragments—from gravel to sand to clay. This is different from igneous rocks, which cool from molten material, and chemical rocks, which precipitate minerals from solution. Sedimentary covers a broader category that includes both clastic and non-clastic types, but the clue about being made of fragments points to the clastic subtype.
