Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO3 and HI are mixed.

A. 2 H+(aq) + SO32-(aq) H2SO3(s)
B. Mg2+(aq) + 2 I-(aq) MgI2(s)
C. 2 H+(aq) + SO32-(aq) + Mg2+(aq) + 2 I-(aq) H2SO3(s) + MgI2(aq)
D. 2 H+(aq) + SO32-(aq) H2O(l) + SO2(g)
E. None of these.

Could someone explain why the answer is E?
