    The best answer would be:

    Intrusive

    If you'd like to know more about this read on:

    Intrusive igneous rocks are formed beneath the Earth, so they are formed from magma. (Not lava because lava is magma that has reached the surface of the Earth)

    These types of rocks cool slowly which allows time for the formation of large crystals and accumulation of different other minerals. The texture is then coarse.

    The opposite is called an extrusive igneous rocks, which are usually fine-grained because it cooled quickly from lava.

    Igneous rock are formed by solidification of lava or magma. There are two type of igneous rock.

    Intrusive Extrusive

    Intrusive rock are formed by solidification of lava or magma inside earth crust. Extrusive rock are formed by solidification of lava or magma on the surface of earth crust.

    Different type of igneous rocks are classified on the basis of their texture. The origin of igneous rock is about 35 km below earth surface.
