B) Crust is the correct answer.
Earth's lower mantle lies just below the crust.
In geology, a crust is the outermost layer of a planet.
The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks.
The crust is underlain by the mantle.
The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.
