Answer:
A. Principle of original horizontality
Explanation:
The principle of original horizontality provides explanation to the way sedimentary rocks are laid in basins of deposition.
The principle emphasizes that sedimentary rocks are originally laid down horizontally in basins of deposition. If we see a tilted rock pattern or any other geometry in rocks, we can attribute it to tectonic activities that must have disturbed the sequence of strata in that area after the deposition and formation of the sedimentary rock.
