Volcanoes usually release molten rock in the form of magma, which is often referred to as "lava" after it reaches the Earth's surface. "Latitude" is a term used to describe the angular distance of a location from the Equator and has no relation to volcanoes. "Larva" refers to the immature form of an insect or an animal and has no relationship to rocks or volcanoes. "Leukemia" is a type of cancer that affects blood cells and is not related to volcanoes or rocks in any way. Therefore, the correct answer is "lava," which is the scientific term used to describe molten rock from volcanoes.
