Which one is dominant mineral in sandstone

Answer: Option C

Quartz is one of the dominant minerals in Sandstone. Most sandstone is composed of quartz or feldspar as they are the most resistant minerals to weathering processes at the Earth’s surface.
Quartz is a hard, crystalline mineral composed of silica. The atoms are linked in a continuous framework of silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO₂.
