(C)ANSWER
2KMnO4+3H2SO4⟶K2SO4+2MnSO4+3H2O+5[O]
Since SO2 is a strong reducing agent, it reduces MnMn as denoted by the equation
5SO2+2KMnO4+2H2O⟶2H2SO4+2MnSO4+K2SO4
Both the reactions are viable. Because of the formation of MnSO4 and the disappearance of KMnO4, decolorisation occurs.
But sulphur dioxide reacts with water to produce sulphurous acid and not sulphuric acid.
SO2+H2O⟶H2SO3
Hence, the acidic nature reasoning doesn’t hold good
