Question

where are the tectonic plates located?
a outer core
b lithosphere
c mesosphere
d asthenosphere

Explanation:

Tectonic plates are rigid, massive slabs that make up the Earth's outer, solid layer. The lithosphere consists of the crust and the uppermost rigid part of the mantle, which is where these tectonic plates are situated. The outer core is a liquid metallic layer beneath the mantle, the mesosphere refers to the lower mantle (a solid, high-pressure layer below the asthenosphere), and the asthenosphere is the ductile layer beneath the lithosphere that the plates move on top of.

Answer:

B. lithosphere
