Answer 1

Neither phrasing is perfect, but the intended difference is:

- Law of inclusion: the included fragments (inclusions) are older than the rock that contains them.
- Law of crosscutting: a feature that cuts across other rocks (an intrusion or fault) is younger than the rocks it cuts.

From the given choices, the closest match is: "Intruding objects are older in the law of inclusion."
