The most characteristic feature of clastic sedimentary rocks is "stratification".
<u>Answer:</u> Option A
<u>Explanation:</u>
"Stratification" is an essential characteristic of the sedimentary rocks take place in an igneous rock produced at the surface of the Earth naturally due to volcanic fragmental deposits and flows of lava. It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter.
It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.
