C. The rigid outermost shell of the Earth’s crust is broken into tectonic plates which move above and below each other over millions of years. That movement also causes earthquakes and volcanoes where the plates collide or separate, The Lesser Antilles islands and volcanoes were formed as a result of the subduction of the Atlantic Plate under the Caribbean Plate.
D. One of the underwater volcanoes near Grenada is called Kick ‘em Jenny, the most active volcano in the Antilles Arc.
