B:Oxygen and silicon
Explanation:
Most minerals on the earth's surface contains oxygen and silicon. Silicon and oxygen are the most abundant elements we find in the rock minerals on the earth surface. 
- Silicon and oxygen forms the SiO₄⁻ tetrahedron through which several minerals are formed. 
- These minerals built on the network of the tetrahedron are referred to as silicates. 
- Several silicate minerals are known: 
- Quartz
- Feldspars
- Olivine
- Biotite
