Question

law of inclusion
law of superposition
law of crosscutting
the question is wrong. a is older than b.

Explanation:

The arrow points to feature E cutting through layer C. The law of crosscutting states that a geologic feature that cuts through another is younger than the feature it cuts. The law of superposition applies to horizontal layers, and the law of inclusion applies to fragments within a rock. The option claiming A is older than B is irrelevant here.

Answer:

Law of crosscutting
