Correct answer
AStatement I is correct but statement II is incorrect.

Step-by-step explanation

A disproportionation reaction is a reaction in which the same element is simultaneously oxidized and reduced. In this type of reaction, a single substance gives two products, one is oxidized while the other is reduced.

S1:S8+12OH4S2+2S2O32+6H2O

S2:ClO4 cannot undergo disproportionation reaction as chlorine is present in its highest oxidation state.

Hence, statement I is correct and II is incorrect.
