The correct answer is D. the volcanic eruptions.In recent studies and research on the water on our planet and how it came to be, the scientists were able to find new evidence that suggest that not only do the comets and asteroids contributed to the existence of water on our planet, but also the volcanoes.The volcanoes are actually releasing to the atmosphere the material in the deepest part of the Earth, the mantle layer.
