The correct statement that explains how hydrothermal vents are created is: Exposure to magma and underwater volcanoes caused by separating and colliding plates create areas of super-heated water.
Hydrothermal vents typically form along mid-ocean ridges where tectonic plates are moving apart, allowing seawater to penetrate into the Earth's crust and come into contact with magma, resulting in super-heated water, which is then expelled through vents.
