Correct answer is b ( by their dominant processes that formed them ) .
There are two different ways that rocks are often classified; the first is based on the processes by which they form, in which rocks are classified as either sedimentary, igneous, and metamorphic.
Through the process of erosion, these fragments are removed from their source and transported by wind, water, ice, or biological activity to a new location. Once the sediment settles somewhere, and enough of it collects, the lowest layers become compacted so tightly that they form solid rock.
