The Moon, Mercury, and Mars do not have plate tectonics because

B) they have no oceans for subduction and seafloor spreading to occur in
C) impacts have filled in the plate boundaries essentially turning the process off
D) their crusts have dried up and thickened so the crust cannot be broken up into plates
