granite originated
in the "throat" of a volcano
by solidification of subsurface magma
by erosion of other rocks
by solidification of surface magma

by solidification of subsurface magma

Explanation:

Granite is formed by the process of the slow crystallization of the magma below the ground surface of the earth and is in the composition of mainly the natural quartz, feldspar and has substantial amounts of mica and other components also. The origin of this granite is with the oceanic crust sand contain the mafic rocks like the basalts and gabbro, This rock occurs for the extreme metamorphism and by the fluids that bring in the elements of the potassium ad that remove the other elements like the calcium.
