The lithosphere is made up of the Earth's crust and the uppermost part of the mantle. This means that the lithosphere is made up of both igneous rocks (formed from cooled magma) and metamorphic rocks (formed by the transformation of existing rocks under high pressure and temperature).

Let's consider the options:

* Igneous rocks: These are definitely part of the lithosphere.

* Sedimentary rocks: While sedimentary rocks form on the Earth's surface, they are often found within the lithosphere, as they can become buried and lithified.

* Metamorphic rocks: These are also a component of the lithosphere.

Therefore, the answer is none of the above. All of the listed rock types can be found in the lithosphere.
