Areas along tectonic plate edges are usually prone to volcanic eruptions. Areas like this in the ocean can develop large islands during volcanic activity. Out of which rock are these islands most likely formed? A. igneous rock, formed when liquid magma erupts onto Earth's surface where it cools and hardens B. igneous rock, formed when sediments from volcanic eruptions collect and cement into layers C. metamorphic rock, formed when sediments from volcanic eruptions collect and cement into layers D. metamorphic rock, formed when liquid magma creates high temperatures and pressures on Earth's surface​
