Sedimentary rocks are usually defined as those rocks where the sediments are deposited, thereby undergone compaction and lithification. These rocks are comprised of fossils at different places. It is because they are soft sediments and the fossilized materials are preserved in it.
The sediments or the broken rock fragments are formed due to the combination of weathering and erosion process, and these sediments are then transported to some other places by the agents such as wind, water, and ice.
After these sediments are deposited in a new place they are subjected to compaction and often minerals are embedded on it, and after solidification, gives rise to the formation of sedimentary rocks.
Thus, the correct answer is option (1).
