Four laws or principles are involved with the study of stratigraphy. They are law of original horizontality, law of superposition law of original lateral continuity, and law of cross-cutting relationships.

Answers that apply: 1, 2, and 4 or the first, second, and fourth option.

Option (1), (2) and (4) are the correct

Explanation:

According to the Steno, the four laws that deals with the study of stratigraphy are as follows-  

Law of Superposition- this law states that in a geochronological sequence the rock layers that are present at the top are the youngest and the rock layers that lies at the bottom are the oldestLaw of Original horizontally- this law states that the sediments usually gets deposited in a horizontal manner due to the influence of gravityLaw of Cross-cutting relationship- this law states that in a particular area when the igneous bodies (such as batholith, plutons etc) intrudes other rocks, then these intruding features are generally younger than the rocks which it cuts, maintaining a cross-cutting relationshipLaw of lateral continuity- this law states that the the sediments at first are deposited and extended laterally in every direction until they meet another geological feature that interrupts its path of lateral extension
