What type of rock is formed from the cooling and solidification of molten magma?

Sedimentary
Metamorphic
Igneous
Crystalline

The correct answer is: Igneous

Igneous rocks are formed when molten magma cools and solidifies. This process usually occurs beneath the Earth's surface, cooling slowly and forming large crystal structures. On the other hand, sedimentary rocks are formed from the accumulation and compaction of sediments, and metamorphic rocks are formed from the alteration of preexisting rocks due to heat and pressure. Crystalline rocks may contain crystals, but they are not necessarily formed from molten magma. Therefore, the correct answer is C Igneous.
