Hey there!
Here is your answer:
The proper answer to this question is "pressure, deposition, and compaction".
Reason:
Sedimentary are formed by pressure, deposition, compaction. Which should be in one of your answer choices.
Also....
This would help you strike out options you don't need, igneous rocks are formed by cooling of magma or lava, and metamorphic rocks are formed by heat and pressure under the Earths surface.
If you need anymore help feel free to ask me!
Hope this helps!
