D. law of crosscutting relationships
Explanation:
The law of cross-cutting relationships is applicable to an igneous intrusion that goes through a sedimentary rock.
This law is one of the laws used in relative dating of rock sequences based on the order through which they form in nature.
- The law states that "geologic features such as igneous intrusion, faults, joints are younger than the rocks they cut through".
- In a sequence of strata, the intrusion is always younger than the rock it passes through.
- Faults which are the fractures in rocks are also younger than the rocks they cut through.
