- AZeolites
- BUltramarines
- ✓Feldspars
- DBeryls
✓
Answer
Correct option: C.
Feldspars
c
The feldspars are most abundant aluminosilicate minerals in the Earth surface. The silicon atoms and aluminium atoms occupy the centres of interlinked tetrahedra of $SiO_4^{-4}$ and $AlO_4^{-5}$ . These tetrahedra connect at each corner to other tetrahedra forming an intricate, three dimesional, negatively charged framework. The sodium cations sit within the voids in this structure
