The grains of sedimentary rock a. are cemented together c. are often displayed in more than one size b. form an interlocking texture d. are usually large

The grains of sedimentary rock are cemented together. For different sediments to change into a sedimentary rock, they have to be compacted together by the process of cementation. These sediments originate from the processes of weathering and rock erosion, and are transported by water before cemented together to form a sedimentary rock.
