Given below are two statements:
Statement (I): Olivine is least stable.
Statement (II): Has independent silica tetrahedron and held together by forming bonds with hydrolysable Magnesium or oxidizable Iron.
In light of the above statements, choose the most appropriate answer from the options given below:

Correct option is A

Olivine is among the least stable minerals at the Earth’s surface due to its simple crystal structure and high reactivity. It is made up of independent silica tetrahedrons linked by metallic ions like Mg²⁺ and Fe²⁺, which are easily leached or oxidized. Both statements are scientifically accurate.
