(A) : SO2 acts as oxidant as well as reductant.It is resonance stabilised and shows sp2 hybridisation.
(B) : SO3 acts as a oxidant.It is resonance stabilized and shows sp2 hybridisation.
(C) : O3 acts as a oxidant.It is resonance stabilized and shows sp2 hybridisation.
(D) : H2S acts as a reductant.It has minimum boiling point and shows sp3 hybridisation.
(E) : H2O has maximum boiling point and shows sp3 hybridisation.
