Layer 2 and layer 9 are the same relative age.

Explanation:

The statement that best describes the rock layers is that Layer 2 and layer 9 are the same relative age..

The relative age is used in placing sedimentary rocks in order of their occurrence.

To do this, we apply the sedimentary laws.

The ones applicable here are:

Principle of superposition states that in an undisturbed sequence, the oldest layer is at the base and youngest on top.
Principle of cross cutting states that a fault and intrusion are younger than the rocks they cut through.
Principle of fossil and fauna succession states that fossils and fauna succeed on another in a determinable form.

We see that layers 2 and 9 have the same fossil and are the same lithological units.
