If both the Assertion and Reason are incorrect.

(D) The Assertion is incorrect because the dinegative anion of sulphur $(S^{2-})$ is actually very common (e.g.,in metal sulphides like $ZnS$,$FeS$),whereas the formation of $O^{2-}$ is energetically demanding due to high electron-electron repulsion in the small oxygen atom.The Reason is also incorrect because the covalency of oxygen is generally two,but this is not the reason for the stability or commonality of its anions.Therefore,both the Assertion and the Reason are incorrect.

$A$ sulphate of a metal $(A)$ on heating evolves two gases $(B)$ and $(C)$ and an oxide $(D).$ Gas $(B)$ turns $K_2Cr_2O_7$ paper green while gas $(C)$ forms a trimer in which there is no $S-S$ bond. Compound $(D)$ with $HCl$ reacts to form a compound $(E)$ which exists as a dimer. Compounds $(A)$,$(B)$,$(C)$,$(D)$ and $(E)$ are respectively:
