Which term best describes what a plate is made of? a. mantle b. lithosphere c. oceanic crust d. continental crust

The term that best describes what a plate is made of is 'lithosphere'.

Explanation:

The oceanic crust and the continental crust together make up the lithosphere. A plate can be both, a continental plate or an oceanic plate, which are both ultimately a part of the lithosphere. The lithosphere is a non-uniform layer that lies and floats above the asthenosphere (the uppermost layer of the mantle). The floating of the lithosphere is due to the non-uniformity of the layer, which is because the layer is divided in number of plates.
