D.

sodium trioxocarbonate (IV).

Correct answer is B

The chemical formula for sodium tetraoxosulphate (VI) is Na2SO4. It is also known as sodium sulfate. This compound does not have any water molecules as part of its crystal structure, making it anhydrous. So, it is an example of a crystalline substance that does not possess water of crystallization.
