Answer : Option B
Explanation :
The igneous rocks are formed due to granitisation. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Granitization, formation of granite or closely related rocks by metamorphic processes, as opposed to igneous processes in which such rocks form from a melt, or magma, of granitic composition.
