e-lub [12.9K]

Answer:

Option D, erosion, deposition, compaction, cementation

Explanation:

Sedimentary rocks are formed from the eroded soil. Therefore, erosion is the first step in formation of sedimentary rocks.  

The eroded soil or rock is carried by carrier agents such as wind, water etc. and deposited at some place where it gets compacted under its own weight. After deposition and compaction, physio-chemical processes take place to produce chemical bonding between the deposited granular particles. Chemical interactions causes cementation of the compacted material  

Hence, option D is correct
