Answer:All of the sedimentary units must have been deposited and lithified before being cut by the fault.

Explanation:What is the principle of cross-cutting relationships?

Geologic features which comes after the rock has formed and cut through it are what result to a cross cutting relationship. This rocks which cuts through such as faults are younger than the host rock or the rock that they cut through, because for them to cut through it it has to have existed before the Intrusion. Magma is usually the substance which pushes and cut through rocks.

Lithification, means the rock are converted into rocks from sediments.
