Solution
The correct option is C Oxygen
More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars and alkali feldspar. Other common silicate minerals are quartz (12%) pyroxenes (11%), amphiboles (5%), micas (5%), and clay minerals (5%). The rest of the silicate family comprises 3% of the crust. Only 8% of the crust is composed of non-silicates — carbonates, oxides, sulfides, etc.
All silicate have the significantly high amount of the Oxygen elemental proportion which cause to give the most abundant element of the Earth crust and fallowed by the Si itself.
