which of the following is a true statement about tectonic plates?
a.they located in the molten layer beneath the earth first.
b.all tectonic plates are located at the earth's core
c.they're located approximately 10 meters below the surface of the ocean.
d.all of the earths landmass rests on tectonic plates.

I would go with D as it is closest to correct. Every part of the surface of the Earth is a tectonic plate though. The plates vary in thickness, but all of the surface of the Earth is made up of tectonic plates, including the parts under the ocean. Technically, the Earth's landmass does not rest on the tectonic plates, it IS the tectonic plates, but it is the closest to correct here in my opinion.

The true statement is - d. all of the earth's landmass rests on tectonic plates.

The Earth’s lithosphere is a rigid outer part of the earth comprise of crust and top or upper mantles. The lithosphere is made up of tectonic plates. It constitutes all floor plates including oceanic floor plates and continental plates.

The tectonic plates are present on the top of the hot molten layer of the mantle.
It starts at the seafloor of the ocean.
As it is the part of the lithosphere it all landmasses rest on tectonic plates
Tectonic plates contain sediments that contain information about the Earth’s history

Thus, the true statement is - d. all of the earth's landmass rests on tectonic plates.
