The tetrahedral structure that forms the backbone of all silicate minerals is composed of silicon and option(b) i.e, oxygen
The tetrahedron-shaped silica chemical structure. It comprises a core silicon atom that connects with four oxygen atoms on both sides. The tetrahedron-shaped geometric figure that is drawn around this configuration has four sides, each of which is an equilateral triangle.
Silicon and oxygen make up the silica tetrahedron, which serves as the base for all silicate crystals. In all sorts of rocks and everywhere in the world, the mineral quartz, SiO2, is formed. In deposited rocks, it manifests as sand grains, in igneous and metamorphic rocks, as crystals, and in veins that cut through all different types of rocks. These veins occasionally contain gold or other precious metals. It is widely known that up until the late 1700s, it was simply known as rock crystal. Quarts belong to a class of minerals known as silicates, all of which include silicon and oxygen in varying amounts. The majority of the minerals in the crust of the planet are silicates, and most estimates place 97 percent of the mantle and 95 percent of the crust in the crust.
