Solution
The correct option is D Onyx
Quartz, tridymite and cristobalite are all crystalline forms of silica however, onyx is a crypto-crystalline form of silica (Cryptocrystalline is a rock texture made up of such minute crystals that its crystalline nature is only vaguely revealed even microscopically by transmitted polarized light). Keisulghur is an amorphous form of silica.
