Which of the following equation is correct? Can be more than one.

There are actually no disproportionation reaction in the question. They are all incomplete and unbalanced.
Example of a disproportionate reaction:
[tex]Cl_{2(g)}+2OH_{(aq)}^-\rightarrow Cl_{(aq)}^-+ClO_{(aq)}^-+H_2O[/tex]For this reaction the chlorine atom on the reactant side as an oxidation state of 0. It gets reduced to -1 in Cl- and oxidized to +1 in ClO3-
