Igneous rocks form primarily **A from the cooling of magma**.
When magma, which is molten rock beneath the Earth's surface, cools and solidifies, it forms igneous rocks. This process can occur either beneath the Earth's surface, resulting in intrusive (or plutonic) igneous rocks like granite, or on the surface after a volcanic eruption, leading to extrusive (or volcanic) igneous rocks such as basalt.
Options B, C, and D refer to processes associated with sedimentary and metamorphic rocks, respectively. Sedimentary rocks form from the cementing of sediments, while metamorphic rocks form from the modification (or metamorphism) of existing rocks due to heat and pressure. Evaporation can lead to the formation of certain types of sedimentary rocks (like salt deposits) but does not directly produce igneous rocks.
