Choose the description that matches the law of included fragments.

Anything cutting across a rock layer is younger than the layer it cuts across.

The Pieces of rock found within other layers are always older than the layer itself.

Metamorphic rock is older than igneous rock because it is always lower in the geologic column.

The exact age of a sedimentary rock layer can be found using the layers above and below it, even if the layers are not in their original positions.
