Answer: Option C

Solution(By Examveda Team)

Quartzite is metamorphosed from Sandstone. Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism. These conditions recrystallize the sand grains and the silica cement that binds them together.
