* Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

* Rhyolite is an extrusive igneous rock, meaning it forms from lava that erupts onto the Earth's surface.

The other options are:

* Limestone: A sedimentary rock formed from the accumulation of marine organisms' shells and skeletons.

* Slate: A metamorphic rock formed by the transformation of shale under heat and pressure.

* Shale: A sedimentary rock formed from the compaction and cementation of mud and clay.
