What does the crust refer to?

Explanation:
Crust refers to the surface and outermost layer of the Earth. It is the rigid shell that sits atop the mantle and includes two main types: continental crust, which is thick and less dense with granitic rocks, and oceanic crust, which is thinner and more dense with basaltic rocks. This outer layer is where the rocks, soils, and minerals we study and mine reside, and it forms the boundary above the mantle at the Moho. The other options describe deeper or unrelated parts of the Earth or atmosphere.
