The correct answer is E.
Explanation
- Fe2(SO4)3 contains sulfate ions $SO_4^{2-}$. Three sulfates give $3\times(-2)=-6$, so two iron atoms must provide $+6$ total, i.e. $Fe^{3+}$. Therefore Fe2(SO4)3 is iron(III) sulfate, not iron(III) sulfide.
- Iron(III) sulfide (with $S^{2-}$) would have formula Fe2S3.
- The other pairs are correct: FeSO4 = iron(II) sulfate, Fe2(SO3)3 = iron(III) sulfite, FeS = iron(II) sulfide, FeSO3 = iron(II) sulfite.
