The layer that contains the crust and the uppermost mantle is the:

Explanation:
The lithosphere is the rigid outer shell that includes both the crust and the uppermost part of the mantle, forming the tectonic plates. The upper mantle present beneath the crust is still part of this solid, brittle layer, while the layer below—the asthenosphere—is weaker and allows plate movement. So, crust plus the upper mantle together define the lithosphere. The core lies deep inside the Earth, and the asthenosphere sits beneath the lithosphere rather than containing the crust.
