The correct answer is; B) the oceanic and continental crust only
A tectonic plate consists of the oceanic and continental crust only
A tectonic plate is a large, irregularly shaped slab of solid rock, which is usually made up of both continental and oceanic crust. The continental crust (sial) is composed mainly of lower-density felsic granitic rocks, while the oceanic crust (sima) is composed mainly of mafic basaltic rocks. Tectonic plates differ greatly in size and thickness. The Pacific and Antarctic Plates are among the largest.
