Will give you ! a section of earth's crust and solid upper mantle is called a. pangaea b. a continent c. a tectonic plate d. the lithosphere

Actually, the answer is C. Tectonic Plate.

Explanation:

Tectonic plates are made up of the Earth's Crust and the upper part of the mantle layer underneath the Earth's crust. But, together they would make up the lithosphere . So, the lithosphere is both of them combined, it's not asking on what makes up the whole layer but a section of this layer.  I hope I did an OK job at explaining!
