The correct answer is A. 60%. Around 60% of the Earth's volcanic activity occurs underwater. These underwater volcanic features are known as hydrothermal vents, where water is heated by geothermal energy from the Earth's core. The most active volcanic areas under the ocean are situated at mid-ocean ridges where tectonic plates are spreading apart.
