Explanation : Analyze the given tetrameric anion $\left({\mathrm{Si}}_4{\mathrm{O}}_{10}\right)$ structure to determine its total charge, shared/unshared oxygen atoms, and planarity.

Concept : (Geometry & properties of Si₄O₁₀ )

A tetrameric silicate anion consists of four SiO₄ tetrahedra linked via oxygen atoms. Each SiO₄ unit has a -4 charge, and due to sharing of oxygens, the total charge of the anion becomes -10. It has three shared oxygen atoms (bridging) and ten unshared oxygen atoms (non-bridging). The tetrahedral geometry makes it non-planar. Hence, all given statements are correct. Answer: Option D (All of the above). Final Answer – Option(D)
